Compute charge distribution for 2D electrostatic problem by Method of moment function in Metlab

Compute charge distribution for 2D electrostatic problem by Method of moment function [charge,sigma] = MoM2D(xs,ys,xe,ye,phi) %Arguments: % xs = x-coordinate for starting points % ys = y-coordinate for starting points % xe = x-coordinate for ending points % ye = y-coordinate for ending points % Returns % sigma = charge density for each element % charge = total charge on each element xobs = 0.5*(xs+xe); % Observation Points yobs = 0.5*(ys+ye); h = sqrt((xe-xs).^2+(ye-ys).^2); % Length of elements % Loop over elements for k = 1:length(xs) s = (((xobs-xs(k))*(xe(k)-xs(k)))+((yobs-ys(k))*(ye(k)-ys(k))))/(h(k))^2; d = sqrt((xobs-xs(k)).^2+(yobs-ys(k)).^2-(s.^2*h(K)^2)+1e-24); xis = -s*h(k); xie = (1-s)*h(k); temp = 0.5*xie.*log(xie.^2+d.^2) ... - xie + d.*atan(xie./d) ... -0.5*xis.*log(xis.^2+d.^2) ... - xis + d.*atan(xis./d) ... A(:,k) = temp(:)/(2*pi*8.854187))); end sigma = (A\phi')'; % Charge density

Concept of Mutual Funds

Concept of Mutual Funds A mutual fund is a trust that pools the savings of number of investors who share a common financial goal. The money thus collected is than invested in capital market instruments such as shares, debentures and other securities. The income earned through these investments and capital appreciations realized are shade by its unit holders in proportion to the number of units owned by them. Thus a mutual fund is the most suitable investment for the common man as it offers an opportunity to invest in a diversified, professionally managed basket of securities at a relatively low cost. Definition Mutual funds are associations or trusts of public members who wish to make investment in the financial instruments or assets of the business sector or corporate sector for the mutual benefit of its members. The funds collects the money of these members from their saving and invests them in a diversified portfolio of financial assets with a view to reduce risks and to maxi

What are the Key differences between IPv4 and IPv6.

What are the Key differences between IPv4 and IPv6. IPv4 Source and destination addresses are 32 bits (4 ytes) in length. IPsec header support is optional. No identification of packet flow for prioritized delivery handling by routers is present within the IPv4 header. Fragmentation is performed by the sending host and at routers, slowing router performance. Has no link-layer packet-size requirements and must be able to reassemble a 576-byte packet. Header includes a checksum. Header includes options. ARP uses broadcast ARP Request frames to resolve an IPv4 address to a link-layer address. Internet Group Management Protocol (IGMP) is used to manage local subnet group membership. ICMP Router Discovery is used to determine the IPv4 address of the best default gateway and is optional. Broadcast addresses are used to send traffic to all nodes on a subnet. Must be configured either manually or through DHCP for IPv4. Uses host address (A) resource records in the Domain Name S
