Dear Students/Parents
We at 'Apex Institute' are committed to provide our students best quality education with ethics. Moving in this direction, we have decided that unlike other expensive and 5star facility type institutes who are huge investors and advertisers, we shall not invest huge amount of money in advertisements. It shall rather be invested on the betterment, enhancement of quality and resources at our center.
We are just looking forward to have 'word-of-mouth' publicity instead. Because, there is only a satisfied student and his/her parents can judge an institute's quality and it's faculty members coaching.
Those coaching institutes, who are investing highly on advertisements, are actually, wasting their money on it, in a sense. Rather, the money should be invested on highly experienced faculty members and on teaching gears.
We all at 'Apex' are taking this initiative to improve the quality of education along-with each student's development and growth.
Committed to excellence...
With best wishes.

Method of Moment analysis of a printed Archimedian Spiral antenna Piyush Kashyap
A single arm Archimedean spiral printed on a grounded dielectric substrate is analyzed using the method of moments. Piecewise sinusoidal subdomain basis and test functions are used over curved segments that exactly follow the spiral curvature. Results for the input impedance obtained using the curved segmentation approach on MATLAB are compared with those obtained after simulating the model on FEKO. A comparison with published results shows that the curved segment model requires fewer segments and is therefore significantly more computationally efficient than the linear segmentation model.

Harnessing WebAssembly for Real-time Stateless Streaming PipelinesChristina Lin
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
The Internet of Things (IoT) is a revolutionary concept that connects everyday objects and devices to the internet, enabling them to communicate, collect, and exchange data. Imagine a world where your refrigerator notifies you when you’re running low on groceries, or streetlights adjust their brightness based on traffic patterns – that’s the power of IoT. In essence, IoT transforms ordinary objects into smart, interconnected devices, creating a network of endless possibilities.
Here is a blog on the role of electrical and electronics engineers in IOT. Let's dig in!!!!

It consists of cw radar and fmcw radar ,range measurement,if amplifier and fmcw altimeterThe CW radar operates using continuous wave transmission, while the FMCW radar employs frequency-modulated continuous wave technology. Range measurement is a crucial aspect of radar systems, providing information about the distance to a target. The IF amplifier plays a key role in signal processing, amplifying intermediate frequency signals for further analysis. The FMCW altimeter utilizes frequency-modulated continuous wave technology to accurately measure altitude above a reference point.

field at point P has the same magnitude as the net magnetic field at the center of the
pipe but is in the opposite direction.

9-3 An electron is shot into one end of a solenoid. As it enters the uniform magnetic
field within the solenoid, its speed is 800 m/s and its velocity vector makes an angle
of 30°with the central axis of the solenoid. The solenoid carries 4.0 A and has 8000
2. turns along its length. How many revolutions does the electron make along its helical
path within the solenoid by the time it emerges from the solenoid's opposite end? (In a
real solenoid, where the field is not uniform at the two ends, the number of
revolutions would be slightly less than the answer here.)
Sol:
As the problem states near the end, some idealizations are being made here to
keep the calculation straightforward (but are slightly unrealistic). For circular
motion (with speed, v, which represents the magnitude of the component of the
velocity perpendicular to the magnetic field [the field is shown in Fig. 29-19]),
the period is (see Eq. 28-17)
T = 2r/v = 2m/eB.
Now, the time to travel the length of the solenoid is /t L v where v|| is the
component of the velocity in the direction of the field (along the coil axis) and is
equal to vcos where = 30º. Using Eq. 29-23 (B = 0in) with n = N/L, we
find the number of revolutions made is t/T = 2.6 106

9-4 Figure 2 shows a cross section of a long cylindrical conductor of radius a = 4.00
cm containing a long cylindrical hole of radius b = 1.50 cm. The central axes of the
cylinder and hole are parallel and are distance d = 2.00 cm apart; current i = 5.25 A is
uniformly distributed over the tinted area. (a) What is the magnitude of the magnetic
field at the center of the hole? (b) Discuss the two special cases b = 0 and d = 0.
Sol:
(a) The magnetic field at a point within the hole is the sum of the fields due to
two current distributions. The first is that of the solid cylinder obtained by filling
the hole and has a current density that is the same as that in the original cylinder
(with the hole). The second is the solid cylinder that fills the hole. It has a current
density with the same magnitude as that of the original cylinder but is in the
opposite direction. If these two situations are superposed the total current in the
region of the hole is zero. Now, a solid cylinder carrying current i, which is
uniformly distributed over a cross section, produces a magnetic field with
magnitude

at a distance r from its axis, inside the cylinder. Here R is the radius of the

4. This correctly gives the field of a solid cylinder carrying a uniform current i, at a
point inside the cylinder a distance d from the axis. If d = 0 the formula gives B =

current.
9-5 In Fig. 3, an arrangement known as Helmholtz coils consists of two circular
coaxial coils, each of N turns and radius R, separated by distance s. The two coils
carry equal currents i in the same direction. Show that the first derivative of the
magnitude of the net magnetic field of the coils (dB/dx) vanishes at the midpoint P
regardless of the value of s. Why would you expect this to be true from symmetry?
This accounts for the uniformity of B near P for this particular coil separation.
Sol:
The magnitude of the magnetic field on the axis of a circular loop, a distance z
from the loop center, is given by Eq. 29-26:

where R is the radius of the loop, N is the number of turns, and i is the current.
Both of the loops in the problem have the same radius, the same number of turns,
and carry the same current. The currents are in the same sense, and the fields they
produce are in the same direction in the region between them. We place the origin
at the center of the left-hand loop and let x be the coordinate of a point on the axis
between the loops. To calculate the field of the left-hand loop, we set z = x in the
equation above. The chosen point on the axis is a distance s – x from the center of
the right-hand loop. To calculate the field it produces, we put z = s – x in the
equation above. The total field at the point is therefore
