# Can I calculate Sharpe ratio by running over many samples?

I have an algorithm that I am backtesting 200 times. It trades over 200 trading days per iteration.

My sharpe ratio is calculated as follows:

sharpe_ratio = (results['Reward'].mean() - 3) / results['Reward'].std()

Where 3 is my risk free rate of return. Is it valid to calculate the returns this way and use them to calculate my sharpe ratio?

• Assuming you are trying to determine your max Sharpe ratio for a portfolio of assets, 200 iterations is way too small. I don't think I ever use less than 100k iterations when doing any optimization whether it be a mean-variance optimization or something more robust. Without any more information, there is no way to tell if your returns are correct or not. Annualizing Sharpe is customary. Being that you are taking the mean of what looks to be a pandas dataframe series, I assume it has not been annualized...you need to use annualized returns and annualized volatility.

# Probability using Bayes Rule

I had a question of probability in one of my tests which I couldn't solve. I think that it could be solved using Bayes rule.

I am not looking for the exact solution but if anyone could explain the concept underlying the tricky problem would be really helpful.

Here is the question -

I have two boxes containing apples and banana. One box contains 3 times the number of bananas as apples. Another box contains 3 times the number of apples as bananas. I chose one box at random and from that box chose 5 fruits with replacement. I got 4 apples and 1 banana. What is the probability that we select the basket mainly with apples?

You have two boxes $B_1$ and $B_2$, where $P(Apple) = 0.25$ for $B_1$ and $P(Apple) = 0.75$ for $B_2$.

You observe data $D$, where you do 5 draws and get 4 apples and 1 banana.

You can formulate your question using the Bayes rule to calculate the probability that you picked box 2:

$$P(B_2|D) = \frac{P(D|B_2) * P(B_2)}{P(D|B_2) * P(B_2) + P(D|B_1) * P(B_1)}$$

Here the priors (of choosing either box) are the same:

$$P(B_1) = P(B_2) = \frac{1}{2}$$

And both likelihood functions (for box 1 and 2) follow a binomial distribution:

$$P(D|B_i) \stackrel{}{\sim} Binomial(n,k) = C(n,k)* p_i^k * (1-p_i)^k$$

where $C(n,k)$ is the combination, and $p_i^k$ is the probability of picking an apple for box $i$.

So now you can just plug in the numbers to the top equation and get the solution for yourself.

# The rungekutta package

[ Tags: bsd3, library, numeric ] [ Propose Tags ]

This package contains a collection of explicit Runge-Kutta methods of various orders, some with fixed-size steps (no error estimate) and some intended for adaptive stepsize (ie, they include an error estimate). There are a couple of test programs which include some adaptive stepsize control, however there is not yet any such routine in the library itself. There is not yet much in the way of documentation. It's version 1.0.2 because the initial version wasn't cabalized.

## Properties

## Modules

#### Maintainer's Corner

For package maintainers and hackage trustees

[back to package description]
This is a small module collecting about a dozen Runge-Kutta methods
of different orders, along with a couple of programs to exercise them.

Build and run testrk, volterra, volterra2, and arenstorf:

o   testrk exercises all of the methods in a non-adaptive way,
solving a test problem with a known analytic solution,
to check convergence. (This was what first indicated that
there was a problem with the Fehlberg 7(8) listing in HNW.)

o   volterra uses a non-adaptive method to solve the Lotka-Volterra
equations from t=0 to t=40: either from a built-in starting point,
or from a starting point specified on the command line.

o   volterra2 does the same, except it uses an adaptive solver

o   arenstorf solves the restricted 3-body problem (earth+moon+satellite)
using an adaptive solver with some specific initial conditions
which yield periodic orbits

The volterra2 and arenstorf examples use an "oracle" function to
decide what is a good step size. Right now that oracle function is in
each test file; arguably it should be in the RungeKutta module.
Eventually it will be, but I haven't spent much time yet on making
that oracle especially good.

## Walking Paths to and from a Goal Differ: On the Role of Bearing Angle in the Formation of Human Locomotion Paths

The path that humans take while walking to a goal is the result of a cognitive process modulated by the perception of the environment and physiological constraints. The path shape and timing implicitly embeds aspects of the architecture behind this process. Here, locomotion paths were investigated during a simple task of walking to and from a goal, by looking at the evolution of the position of the human on a horizontal (x,y) plane. We found that the path while walking to a goal was not the same as that while returning from it. Forward-return paths were systematically separated by 0.5-1.9m, or about 5% of the goal distance. We show that this path separation occurs as a consequence of anticipating the desired body orientation at the goal while keeping the target in view. The magnitude of this separation was strongly influenced by the bearing angle (difference between body orientation and angle to goal) and the final orientation imposed at the goal. This phenomenon highlights the impact of a trade-off between a directional perceptual apparatus—eyes in the head on the shoulders—and and physiological limitations, in the formation of human locomotion paths. Our results give an insight into the influence of environmental and perceptual variables on human locomotion and provide a basis for further mathematical study of these mechanisms.

The blocking probability of a network is a common measure of its performance. There exist means of quickly calculating the blocking probabilities of Banyan networks; however, because Banyan networks have no redundant paths, they are not inherently fault-tolerant, and so their use in large-scale multiprocessors is problematic. Unfortunately, the addition of multiple paths between message sources and sinks in a network complicates the calculation of blocking probabilities. A methodology for exact calculation of blocking probabilities for small networks with redundant paths is presented here, with some discussion of its potential use in approximating blocking probabilities for large networks with redundant paths.

Free-form surface machining is a fundamental but time-consuming process in modern manufacturing. The central question we ask in this thesis is how to reduce the time that it takes for a 5-axis CNC (Computer Numerical Control) milling machine to sweep an entire free-form surface in its finishing stage. We formulate a non-classical variational time-optimization problem defined on a 2-dimensional manifold subject to both equality and inequality constraints. The machining time is the cost functional in this optimization problem. We seek for a preferable vector field on a surface to obtain skeletal information on the toolpaths. This framework is more amenable to the techniques of continuum mechanics and differential geometry rather than to path generation and conventional CAD/CAM (Computer Aided Design and Manufacturing) theory. After the formulation, this thesis derives the necessary conditions for optimality. We decompose the problem into a series of optimization problems defined on 1-dimensional streamlines of the vector field and, as a result, simplify the problem significantly. The anisotropy in kinematic performance has a practical importance in high-speed machining. The greedy scheme, which this thesis implements for a parallel hexapod machine tool...

## Orthopyroxene-sillimanite-quartz assemblages: distribution, petrology, quantitative P-T-X constraints and P-T paths

Granulite facies magnesian metapelites commonly preserve a wide array of mineral assemblages and reaction textures that are useful for deciphering the metamorphic evolution of a terrane. Quantitative pressure, temperature and bulk composition constraints on the development and preservation of characteristic peak granulite facies mineral assemblages such as orthopyroxene + sillimanite + quartz are assessed with reference to calculated phase diagrams. In NCKFMASH and its chemical subsystems, peak assemblages form mainly in high-variance fields, and most mineral assemblage changes reflect multivariant equilibria. The rarity of orthopyroxene–sillimanite–quartz-bearing assemblages in granulite facies rocks reflects the need for bulk rock XMg of greater than approximately 0.60–0.65, with pressures and temperatures exceeding c. 8 kbar and 850 °C, respectively. Cordierite coronas mantling peak minerals such as orthopyroxene, sillimanite and quartz have historically been used to infer isothermal decompression P–T paths in ultrahigh-temperature granulite facies terranes. However, a potentially wide range of P–T paths from a given peak metamorphic condition facilitate retrograde cordierite growth after orthopyroxene + sillimanite + quartz...

## Spatial and temporal variability of Cross-Basin acoustic ray paths

Relevância na Pesquisa
26.6%
Approved for public release; distribution is unlimited.; It was suggested by Munk and Forbes (1989) that climate induced changes in ocean temperature may be monitored by measurements of cross-basin acoustic travel time variability. The feasibility of such a monitoring system depends on the spatial and temporal variability of the cross-basin acoustic paths in the presence of ocean variability of many different scales. For this thesis the variations in arrival position, azimuthal arrival angle, ray trajectory and the corresponding changes in travel times along the three- dimensional multipaths due to meso- and gyre scale ocean temperature fluctuations were analyzed. Emphasis was placed on the acoustic paths from Heard Island in the Indian Ocean, the proposed location for the sound source, to the west coast of the United States. An optimal receiver site location was found to exist in the vicinity of Monterey Bay, California. The possibility of a proposed listening site location near Coos Bay, Oregon, was also examined. However, the ray paths to Coos Bay interact with the bottom frequently, thus rendering them less reliable. All the ray traces for this study were carried out using the recently upgraded Hamiltonian raytracing code HARPO...

Provaremos uma fórmula do tipo Itô-Ventzel para caminhos Hölder cujo expoente é maior que 1/3. Os exemplos fundamentais de caminhos onde a fórmula é válida é o movimento Browniano fracionário. Nossa fórmula estende (e coincide) a versão clássica feita por H. Kunita na década de 80. As ferramentas utilizadas residem no contexto dos rough paths seguindo a abordagem de M. Gubinelli. Tais tecnicas começaram a serem desenvolvidas por T. Lyons no final de 90. Como aplicação, estudaremos equações diferenciais dirigidas por caminhos cujo expoente é maior que 1/2 (Sistemas de Young). Onde a idéia aqui é empregar nossa fórmula aplicando o método das caracteristicas nesse contexto, seguindo novamente os trabalhos de H. Kunita.; We prove an Itô-Ventezel type formula for Hölder paths with exponent is greater than 1/3. The most important class of examples of theses paths is given by fractional Brownian motion. Our formula is an extension (and agree) to classic version done by H. Kunita in 80's. The technical tools used rely on rough path theory following M. Gubinelli's approach. Those techniques were developed in the late 90's. by T. Lyons. As an application, we study differential equations driven by paths with exponent greater than 1/2 (Young Systems). The ideia here is to employ our formula together with method of characteristics in this setting...

The present study investigated the longitudinal impact of the Project PATHS, a large-scale curriculum-based positive youth development program in Hong Kong, on the development of adolescents' risk behavior over a period of five years. Using a longitudinal randomized controlled design, eight waves of data were collected from 19 experimental schools in which students participated in the Project PATHS (N = 2,850 at Wave 8) and 24 control schools without joining the Project PATHS (N = 3,640 at Wave 8). At each wave, students responded to measures assessing their current risk behaviors, including delinquency, use of different types of drug, and their intentions of participating in risk behaviors in the future. Results demonstrated that adolescents receiving the program exhibited significantly slower increases in delinquent behaviors and substance use as compared to the control participants. During two years after the completion of the program, differences in youth risk behaviors in the two groups still existed. These results suggest that the Project PATHS has long-term effect in preventing adolescent problem behavior through promoting positive youth development.

As an image of the many-to-one map of loop-erasing operation $\LE$ of random walks, a self-avoiding walk (SAW) is obtained. The loop-erased random walk (LERW) model is the statistical ensemble of SAWs such that the weight of each SAW $\zeta$ is given by the total weight of all random walks $\pi$ which are inverse images of $\zeta$, $\{\pi: \LE(\pi)=\zeta \}$. We regard the Brownian paths as the continuum limits of random walks and consider the statistical ensemble of loop-erased Brownian paths (LEBPs) as the continuum limits of the LERW model. Following the theory of Fomin on nonintersecting LERWs, we introduce a nonintersecting system of $N$-tuples of LEBPs in a domain $D$ in the complex plane, where the total weight of nonintersecting LEBPs is given by Fomin's determinant of an $N \times N$ matrix whose entries are boundary Poisson kernels in $D$. We set a sequence of chambers in a planar domain and observe the first passage points at which $N$ Brownian paths $(\gamma_1,..., \gamma_N)$ first enter each chamber, under the condition that the loop-erased parts $(\LE(\gamma_1),..., \LE(\gamma_N))$ make a system of nonintersecting LEBPs in the domain in the sense of Fomin. We prove that the correlation functions of first passage points of the Brownian paths of the present system are generally given by determinants specified by a continuous function called the correlation kernel. The correlation kernel is of Eynard-Mehta type...

We consider planar quadrangulations with three marked vertices and discuss the geometry of triangles made of three geodesic paths joining them. We also study the geometry of minimal separating loops, i.e. paths of minimal length among all closed paths passing by one of the three vertices and separating the two others in the quadrangulation. We concentrate on the universal scaling limit of large quadrangulations, also known as the Brownian map, where pairs of geodesic paths or minimal separating loops have common parts of non-zero macroscopic length. This is the phenomenon of confluence, which distinguishes the geometry of random quadrangulations from that of smooth surfaces. We characterize the universal probability distribution for the lengths of these common parts.; Comment: 48 pages, 33 color figures.

We study pathwise invariances of centred random fields that can be controlled through the covariance. A result involving composition operators is obtained in second-order settings, and we show that various path properties including additivity boil down to invariances of the covariance kernel. These results are extended to a broader class of operators in the Gaussian case, via the Lo\`eve isometry. Several covariance-driven pathwise invariances are illustrated, including fields with symmetric paths, centred paths, harmonic paths, or sparse paths. The proposed approach delivers a number of promising results and perspectives in Gaussian process regression.

## Positive paths in the linear symplectic group

A positive path in the linear symplectic group $\Sp(2n)$ is a smooth path which is everywhere tangent to the positive cone. These paths are generated by negative definite (time-dependent) quadratic Hamiltonian functions on Euclidean space. A special case are autonomous positive paths, which are generated by time-independent Hamiltonians, and which all lie in the set $\Uu$ of diagonalizable matrices with eigenvalues on the unit circle. However, as was shown by Krein, the eigenvalues of a general positive path can move off the unit circle. In this paper, we extend Krein's theory: we investigate the general behavior of positive paths which do not encounter the eigenvalue 1, showing, for example, that any such path can be extended to have endpoint with all eigenvalues on the circle. We also show that in the case $2n=4$ there is a close relation between the index of a positive path and the regions of the symplectic group that such a path can cross. Our motivation for studying these paths came from a geometric squeezing problem in symplectic topology. However, they are also of interest in relation to the stability of periodic Hamiltonian systems and in the theory of geodesics in Riemannian geometry.; Comment: Latex 26 pages

We study semi-infinite paths of the radial spanning tree (RST) of a Poisson point process in the plane. We first show that the expectation of the number of intersection points between semi-infinite paths and the sphere with radius $r$ grows sublinearly with $r$. Then, we prove that in each (deterministic) direction, there exists with probability one a unique semi-infinite path, framed by an infinite number of other semi-infinite paths of close asymptotic directions. The set of (random) directions in which there are more than one semi-infinite paths is dense in $[0,2\pi)$. It corresponds to possible asymptotic directions of competition interfaces. We show that the RST can be decomposed in at most five infinite subtrees directly connected to the root. The interfaces separating these subtrees are studied and simulations are provided.; Comment: 22 pages

## Counting Dyck paths by area and rank

The set of Dyck paths of length $2n$ inherits a lattice structure from a bijection with the set of noncrossing partitions with the usual partial order. In this paper, we study the joint distribution of two statistics for Dyck paths: \emph{area} (the area under the path) and \emph{rank} (the rank in the lattice). While area for Dyck paths has been studied, pairing it with this rank function seems new, and we get an interesting $(q,t)$-refinement of the Catalan numbers. We present two decompositions of the corresponding generating function: one refines an identity of Carlitz and Riordan; the other refines the notion of $\gamma$-nonnegativity, and is based on a decomposition of the lattice of noncrossing partitions due to Simion and Ullman. Further, Biane's correspondence and a result of Stump allow us to conclude that the joint distribution of area and rank for Dyck paths equals the joint distribution of length and reflection length for the permutations lying below the $n$-cycle $(12...n)$ in the absolute order on the symmetric group.; Comment: 24 pages, 7 figures. Connections with work of C. Stump (arXiv:0808.2822v2) eliminated the need for 5 pages of proof in the first draft

We provide a simple linear time transformation from a directed or undirected graph with labeled edges to an unlabeled digraph, such that paths in the input graph in which no two consecutive edges have the same label correspond to paths in the transformed graph and vice versa. Using this transformation, we provide efficient algorithms for finding paths and cycles with no two consecutive equal labels. We also consider related problems where the paths and cycles are required to be simple; we find efficient algorithms for the undirected case of these problems but show the directed case to be NP-complete. We apply our path and cycle finding algorithms in a program for generating and solving Sudoku puzzles, and show experimentally that they lead to effective puzzle-solving rules that may also be of interest to human Sudoku puzzle solvers.; Comment: 17 pages, 11 figures

We derive a series of results on random walks on a d-dimensional hypercubic lattice (lattice paths). We introduce the notions of terse and simple paths corresponding to the path having no backtracking parts (spikes). These paths label equivalence classes which allow a rearrangement of the sum over paths. The basic combinatorial quantities of this construction are given. These formulas are useful when performing strong coupling (hopping parameter) expansions of lattice models. Some applications are described.; Comment: Latex. 25 pages

## Optimal self-avoiding paths in dilute random medium

Seno, F.; Stella, A. L.; Vanderzande, C.
By a new type of finite size scaling analysis on the square lattice, and by renormalization group calculations on hierarchical lattices we investigate the effects of dilution on optimal undirected self-avoiding paths in a random environment. The behaviour of the optimal paths remains the same as for directed paths in undiluted medium, as long as forbidden bonds are not exceeding the percolation threshold. Thus, overhanging configurations do not alter the standard self-affine directed polymer scaling regime, even above the directed threshold, when they become unavoidable. When dilution reaches the undirected threshold, the optimal path becomes fractal, with fractal dimension equal to $D_{\rm min}$, the dimension of the minimal length path on percolation cluster backbone. In this regime the optimal path energy fluctuation, $\overline{\Delta E}$, can be ascribed entirely to minimal length fluctuations, and satisfies $\overline{\Delta E} \propto L^{\omega}$, with $\omega=1.02 \pm 0.06$ in $2d$, $L$ being the Euclidean distance. Hierarchical lattice calculations confirm that $\omega$ is also the exponent of the leading scaling correction to $\overline E \propto L^{D_{\rm min}}$. Upon approaching threshold, the probability, ${\cal R}$, that the optimal path does not stick entirely on the minimal length one...
The one-dimensional Brownian motion starting from the origin at time $t=0$, conditioned to return to the origin at time $t=1$ and to stay positive during time interval $0 < t < 1$, is called the Bessel bridge with duration 1. We consider the $N$-particle system of such Bessel bridges conditioned never to collide with each other in $0 < t < 1$, which is the continuum limit of the vicious walk model in watermelon configuration with a wall. Distributions of maximum-values of paths attained in the time interval $t \in (0,1)$ are studied to characterize the statistics of random patterns of the repulsive paths on the spatio-temporal plane. For the outermost path, the distribution function of maximum value is exactly determined for general $N$. We show that the present $N$-path system of noncolliding Bessel bridges is realized as the positive-eigenvalue process of the $2N \times 2N$ matrix-valued Brownian bridge in the symmetry class C. Using this fact computer simulations are performed and numerical results on the $N$-dependence of the maximum-value distributions of the inner paths are reported. The present work demonstrates that the extreme-value problems of noncolliding paths are related with the random matrix theory, representation theory of symmetry...

# What is a statistical significance test for two Poisson distributions?

Say that I have two Poisson distributions. These were modelling after count data.

How would I determine statistical significance between these two distributions? That is, how would I determine whether these two poisson distributions are statistically different?

Could I apply any non-parametric test (because they don't assume anything about the distribution of the data)? A simple Google search doesn't seem to provide direct answers.

• When you say you have Poisson distributions ... do you have two Poisson observations each thought to be drawn from a Poisson distribution, or do you have a collection of Poisson observations from each? (How were they obtained? Is there pairing, for example?) – Glen_b Feb 29 '16 at 0:46
• I have poisson observations thought to be from a Poisson distribution and I have estimated the parameters for the Poisson distributions. Now I'd like to determine whether they are statistically different or not. – user46925 Feb 29 '16 at 1:01
• This is a hypothetical question, so I'd love to hear both the paired and unpaired solutions. – user46925 Feb 29 '16 at 1:01
• See significance of difference between two counts (for the unpaired situation) & Non-normally distributed data - Box-Cox transformation? (for the paired situation). Both about @Glen_b's 1.a. – Scortchi - Reinstate Monica Feb 29 '16 at 15:59

Note that Poisson distributions are entirely determined by their parameter, so a test of equality of their mean parameter is a test for whether the distributions are the same.

Some possible tests:

1. If you have two samples which you treat as iid Poisson each with its own parameter, which you want to test for equality of that parameter; in that case you can simply combine all the observations in each group into a single Poisson count.

a. You could condition on the total count and do a test of proportions (a binomial test in exact form, or via normal approximation, or equivalently a chi-squared test). For example, this binomial test is what you get if you do poisson.test on two samples in R.

b. You could do a likelihood ratio test.

(There are a number of other possibilities under this option.)

2. If you don't necessarily want to treat them as Poisson except as a rough approximation (but do treat them as iid), you would keep all the individual values.

a. You could then do a permutation test of the means.

b. You could do a Wilcoxon-Mann-Whitney or even a goodness of fit test (e.g. a Kolmogorov-Smirnov test) but you will have to deal with the discreteness of the distributions.

c. If you expect that the means won't be very small, you could perform (say) a t-test (under the null the samples should have equal variance, so it's not important whether you do the equal-variance version).

3. If instead of being identically distributed, they are of known but different exposures, you could combine into single counts as in option 1, but also combine the exposures into a single exposure for each. You could then follow the approaches in 1.

4. If they have unknown exposure but the exposures of pairs of observations will be the same, you effectively have pairing. You could perform a paired permutation test -- permuting the group labels within each pair (which corresponds to putting + and - signs on each absolute pair difference of counts). You could also do a sign test, or since (under the null) the differences would be symmetric you could consider a signed rank test (again properly accounting for ties).

# Two Large Conducting Plates Are Placed Parallel to Each Other with a Separation of 2⋅00 Cm Between Them. - Physics

ConceptElectric Charges

#### Question

Two large conducting plates are placed parallel to each other with a separation of 2⋅00 cm between them. An electron starting from rest near one of the plates reaches the other plate in 2⋅00 microseconds. Find the surface charge density on the inner surfaces.

#### Solution

Distance travelled by the electron, d= 2 cm
Time taken to cross the region, t = 2×  10-6 s
Let the surface charge density at the conducting plates be σ.
Let the acceleration of the electron be a.
Applying the 2nd equation of motion, we get:

"d" = 1/2 "a""t"^2

=> "a" = (2"d")/"t"^2

This acceleration is provided by the Coulombic force. So,

"a" = "qE"/m = "2d"/"t"^2

=> "E" = (2"md")/"qt"^2

"E"  =  (2 xx (9.1xx10^-31) xx (2 xx 10^-2))/((1.6 xx 10^-19) xx ( 4 xx 10^-12)

E = 5.6875 × 10-2 N/C

Also, we know that electric field due to a plate,

"E" = sigma/∈_0

⇒ σ =∈_0 E

⇒ σ = ( 8.85 × 10-12) × ( 5.68 × 10-2 ) C/m2

⇒ σ  = 50.33 × 10-14 C/m2 = 0.503 ×   10-12 C/m2

Is there an error in this question or solution?

# Relation between beamwidth and operating frequency

Radars operating in the X-band have a narrow beamwidth. Radars operating in the S and C bands have a bit more beamwidth than X band radars.

I know that antenna size also plays a major role. My doubt is:

1. Whether the beamwidth is determined only by the operating frequency?
2. Whether it is theoretically possible to have a narrow beam width for S band radar, like X band radar?
3. Similarly, can I have a narrow beamwidth for operating at HF frequencies?

It's theoretically possible to have a narrow beam width at any frequency, but it's the ratio of size of the antenna to wavelength that determines the narrowest possible beam width. So you need either very large antennas, or very small wavelengths. Or both.

There are many relationships like this in physics and engineering.

## Lasers

Lasers have very narrow beam widths, so let's talk about those. Light is just a much higher frequency electromagnetic radiation, so the same physics applies.

You might have heard lasers produce a perfect beam of light, that is one with parallel sides which does not diverge at all. However, this is not possible.

If the objective is to have the smallest beam width, the best kind of physically possible beam is a Gaussian beam. Somewhere along this beam is a waist, the point at which it is narrowest. Usually the waist is the aperture from which light is emitted from the laser.

Away from the aperture, the beam diverges at some angle $\theta$ (in radians). If the wavelength is $\lambda$ and the waist diameter is $w_0$, then that angle is given by:

$$\theta \simeq \frac{\lambda}{\pi w_0}$$

From this equation you can see to decrease the beam width (decrease $\theta$), one can either decrease the wavelength, or make the aperture bigger. It's because the wavelength of light is so small that a common laser pointer, which might have an aperture of only 1mm, can create a beam which appears "perfect" by casual observation.

## Diffraction Limit

The diffraction limit in optical imaging has a similar relationship between sharpness and wavelength. The smallest resolvable feature size $d$ again depends on wavelength, as well as the index of refraction $n$, and the half-angle subtended by the optical objective lens $\theta$.

$$d \simeq \frac {\lambda }{2n\sin {\theta }}$$

Again, making the lens bigger or decreasing the wavelength will allow smaller features to be resolved.

## Antenna Gain and Aperture

Some kinds of antennas have a physical aperture. For example, dish antennas. If we assumed 100% of the energy hitting that aperture was collected by the antenna, then the relationship between aperture area $A$ and gain $G$ is:

$$A = {\lambda^2 \over 4 \pi} G$$

And of course, a higher gain means a higher directivity and a narrower beam width. Real antennas don't capture energy 100% efficiently due to resistive losses, diffraction, shadowing of the dish, and so on, so there's an "aperture efficiency" factor that's added, which is typically around 40% to 80%.

However, there's still the general relationship: increasing gain requires increasing aperture area or decreasing wavelength.
