Filter Bank Based Notch Filter for Interference Cancellation in UWB Systems
Authors: Srivastava Saurabh , Sahu O. P.
Published: January 2023

The primary concern of any communication engineer is the bandwidth of the transmitted or received signal and the noise encountered during the transmission reception process. We analyze the effects of narrowband interference in Multicarrier UWB systems such as short distance IEEE 802.11a system. It is known that the process of narrowband interference cancellation is quite complex especially for ultra-wideband systems due to their power spectral density as low as -41dBm/MHz recommendations by the FCC. We review the model for narrow band interference and use the statistical property of correlation to determine the interference power spectral density. We review the sub band processing of UWB signals and apply notch filtering after measuring the threshold to eliminate the interference. We propose a novel mechanism for generation of the required notch filter using the sub band signals generated after the sub band decomposition of the UWB signal using filter banks. The proposed mechanism may be applied in conjunction with the other filter bank based multicarrier systems that have the advantage of better side-band attenuation of signals than commonly used OFDM system.

Authors: Misra R. K.
Published: January 2023

This paper describes thermal modeling of Vapor Compression Refrigeration System using R134a in primary circuit and AL2O3-Water based nanofluids in secondary circuit. The model uses information of the secondary fluids input conditions geometric characteristics of the system, size of nanoparticles and the compressor speed to predict the secondary fluids output temperatures, the operating pressures, the compressor power consumption and the system overall energy performance. Such an analysis can be conveniently useful to compare the thermal performance of different nano particles (Cu, Al2o3, Tio2 and CuO) based nano fluid as a secondary fluid in a Vapor Compression Refrigeration System. The influence of input variables on the output of the system is presented. Such a model can also be used to design various Components viz. Evaporator, Compressor, Condenser and Throttle Valve for Vapor Compression Refrigeration Systems for any desired cooling capacity. The use of nanofluids as a secondary fluid in vapour compression refrigeration systems was studied and computational simulation program was developed to solve the non linear equations of the system model. Simulation results have shown that for the same geometric characteristics of the system performance increased from 17% to 20% by application of nanofluid as a secondary fluid in VCS.

Authors: Mann Shakti , Khatri Jayesh
Published: January 2023

Kinetic Energy Recovery System (KERS) is a system for recovering the moving vehicle's kinetic energy under braking and also to convert the usual loss in kinetic energy into gain in kinetic energy. When riding a bicycle, a great amount of kinetic energy is lost while braking, making start up fairly strenuous. Here we used mechanical regenerative braking system by means of a flywheel to store the energy which is normally lost during braking, and reuse it to help propel the rider when starting. The rider can charge the flywheel when slowing or descending a hill and boost the bike when accelerating or climbing a hill. The flywheel increases maximum acceleration and nets 10% pedal energy savings during a ride where speeds are between 12.5 and 15 km/hr.

Optimal Bidirectional Battery Charger
Authors: S. Alexander
Published: January 2023

This paper presents a optimal bidirectional battery charger. The proposed charger acts as a current source, i.e., acts in constant current (CC ) mode with a controlled output current in case of deep discharge of a battery, and as a voltage source, i.e., acts in constant-voltage (CV) mode with a controlled output voltage for near-100% battery state of charge. The proposed circuit is universal from the battery voltage point of view, i.e., can charge a battery with any given voltage rating, and adaptive from the optimum charging current requirement viewpoint, i.e., can adapt to the optimum battery charging current. The presented solution uses a magnetically coupled bidirectional converter topology. In order to make the system feedback controlled during the whole cycle of charging, the regulation loop is clamped, and hence, automatic and smooth transition from the CC to CV mode is achieved without the need of any extra switching circuit or control loop. Experimental and simulation results for a 250-W prototype are presented to verify the proposed system. The prototype shows maximum efficiencies of 90.24% under boost mode and 92.7% under buck mode of operation. The performance of the charger is verified using two different 12-V–7-Ah and12-V–32-Ah lead–acid batteries

The present work represents the modeling of nano scale tin indium films by computing the film thickness, mass deposited on the substrate and mass transfer rate with time dependent model using BDF solver. Tin and indium is evaporated from a resistively heated evaporator source at a temperature of 1855 K and 1485 K respectively in a pressure (vacuum) of 100 Pa onto silicon surface held on a fixed surface. The film thickness varies between 144 nm to 164 nm for Tin and 164 nm to 183 nm for Indium across the sample after 60 sec of deposition, with radial symmetry about the midpoint of the source.
The film thickness as well as mass deposited at a point increases linearly with time. Since the angular distribution is of particular interest in this model, by increasing the integration resolution to a maximum value for ensuring the most accurate angular resolution when computing the flux. The surface temperature is required to specifying the temperature of the evaporating tin and indium source using constant elements for turn off the refinement in the post-processing settings. The SEM micrographs of tin and indium at different magnifications shows the 100nm to 1microns grain size along the grain boundaries. Similarly, XRD analysis with Kα (wavelength 1.541874) shows the peaks of intensity at different 2θ angles for different orientations of planes with polycrystalline structure.

Authors: . Elavarasi , Raja G.
Published: January 2023

Deadlocks are an important issue in the design and analysis of communication networks. Wormhole switching is a popular switching technique in direct networks. It refers to a simple flow control system in computer network that is primarily based on fixed links. It also reduces the latency and storage requirements on each node. Deadlock analysis of routing function is a manual and complex task. In the absence of contention, latencies are proportional to the sum of the packet length and the distances to travel. We propose an algorithm to analyze the deadlock in communication networks. The deadlock-free routing algorithm is the first to automatically check a necessary and sufficient condition for deadlock-free routing. Our algorithm performs Effective analysis in this network.

Authors: Sangeetha R. , NandhaKumar S.
Published: January 2023

Cognitive radio (CR) is one of today’s up-and-coming technologies. It facilitates communication because it creates greater efficiencies in mobile networks. CR allows unlicensed (secondary) users to exploit, in an opportunistic or ad hoc manner, the radio communications spectrum allocated to licensed (primary) users. CR is a promising potential solution to the problems caused by inflexibility in spectrum allocation policy, with attendant spectrum shortage. Due to facility in cognitive radio (CR) ad hoc networks, many unlicensed users may acquire different available channels depending on the locations and traffic of licensed users for efficient broadcast operation. By this strategy, proposed work enables the novel unified analytical model to estimate the efficiency of several protocols. First step is decompose the intricate network into a few simpler networks so that the successful broadcast ratio of these simpler networks is straightforward and also obtain successful broadcast ratio of the overall network can be acquired. These systematic models efficiently analyze all protocol without considering their design and specification.

Clodia, Celio e la retorica dell’abbandono (A proposito di Cic. Cael. 61)
Authors: Tedeschi Antonella
Published: January 2023

La ‘retorica dell’abbandono’ si basa su elementi ricorrenti e meccanismi comportamentali divenuti topici, come attestato dalla poesia e dal teatro. Anche l’oratoria vi ricorre. Cicerone, ad esempio, fa rientrare nella topica di un crudelissimum discidium le accuse che Clodia aveva rivolto al suo assistito, Celio (Cic. Cael. 30-31). Il termine discidium diventa, pertanto, funzionale a rendere persuasive le argomentazioni difensive, in quanto vettore dell’idea della violenza della separazione: una violenza in grado di produrre risentimento e devastanti conseguenze emotive che si traducono in parole e azioni mirate a colpire un ex innamorato. La trasformazione dell’affettuosa consuetudo in astiosa simultas, descritta in Cic. Cael. 61, dunque, viene indicata come causa delle azioni intraprese da Clodia contro Celio: un efficace modo per attenuare i crimina attribuiti al giovane e per minare l’attendibilità della teste.

Метою статті визначено теоретичний аналіз особливостей формування громадянських почуттів здобувачів освіти у ході вивчення навчальної дисципліни «Історія України». Завданнями статті передбачено окреслення та описову характеристику тематичних компонентів, які найбільше спрямовані на формування свідомої громадянської позиції та почуттів молодого покоління.

Доведено, що серед основних освітніх напрямів сьогодні найбільш актуальними є патріотичне, громадянське виховання як стрижневі, основоположні, що не лише відповідають нагальним вимогам і викликам сучасності, а й закладають підвалини для формування свідомості нинішніх і прийдешніх поколінь, які розглядатимуть державу як запоруку власного особистісного розвитку, що спирається на ідеї гуманізму, соціального добробуту, демократії, свободи, толерантності, виваженості, відповідальності, здорового способу життя, готовності до змін. Тому формування «нових»  патріотичних та громадянських якостей учнівської молоді полягає у гармонійному поєднанні традиційного виховання минулим і виробленні нових виховних парадигм з урахуванням перспектив розвитку суспільства в цілому.

TOURISM ACCOMODATION INDICATORS’ IMPACT ON THE GDP – A GRANGER CAUSALITY APPROACH
Authors:   “ARTIFEX” University of Bucharest, Bucharest, Romania, Manole Alexandru , Buiga Andrei ,   “ARTIFEX” University of Bucharest, Bucharest, Romania
Published: January 2023

In this paper, the authors study the impact of selected indicators of tourism accommodation on the Gross Domestic Product. The indicators are related to the number of nights spent, therefore they are not directly related to the GDP, thus justifying the choice of Granger causality as method to assess the impact. The fact that most of the variables are found to be not stationary leads to the application of a special technique, adapted to the dataset and software used. The VAR models used do not pass all the specification tests, the authors have chosen a conservative approach, considering the results achieved with caution. Following the application of the methodology, mixed results have been achieved, showing that there is some degree of causality, which cannot be, however, generalized.
