Published: July 2022

This study was carried out to investigate the clinical efficacy of Gegen Qinlian Decoction combined
with a Chinese herbal hot package in the treatment of acute gastroenteritis (AGE), and to analyze the
effects on serum PCT, CRP and IL-6 levels. For this purpose, 100 patients with AGE admitted to the
hospital from January 2019 to January 2022 were selected for the study and randomly divided into
observation and control groups, with 50 cases in each group. Patients in the control group were given
conventional Western medical treatment, while patients in the observation group were treated with
Gegen Qinlian Decoction combined with a Chinese herbal hot package on this basis. The clinical
efficacy, symptom relief time, main symptom scores and serum PCT, CRP and IL-6 levels before and
after treatment were compared between the two groups. Results showed that the total effective rate of
patients in the observation group was significantly higher than that in the control group (P<0.05). After
treatment, the disappearance time of diarrhea, abdominal pain, fever and vomiting was significantly
shorter in the observation group than in the control group (P<0.05). After treatment, the stool properties,
number of stools and abdominal pain symptom scores of patients in both groups were lower than those
before treatment, and the symptom scores of patients in the observation group were lower than those in
the control group (P<0.05). The PCT, CRP and IL-6 levels of patients in both groups were significantly
lower after treatment than before treatment, and the PCT, CRP and IL-6 levels of patients in the
observation group were significantly lower than those in the control group (P<0.05). It was concluded
that the clinical efficacy of Gegen Qinlian Decoction combined with Chinese herbal hot package in the
treatment of AGE is remarkable, which can effectively improve the clinical symptoms and reduce the
inflammatory reaction of patients and is worthy of clinical promotion.
Determining the frequency of Streptococcus pneumoniae carriers and its microbial
resistance in children
Authors: Langhuan  Lei  , Xingyong Wang
Published: July 2022

Streptococcus pneumoniae is a common cause of bacterial infections of the respiratory system, middle
ear infection, bacteremia, meningitis, and pneumonia, especially in children. Due to the lack of
information about the frequency and resistance of Streptococcus pneumoniae to antibiotics, the present
study was performed to determine the frequency of carriers of Streptococcus pneumoniae and its
microbial resistance in children. For this purpose, the current descriptive cross-sectional study was
conducted from November to March 2020 on 554 children aged 2-12 years in kindergartens and
schools. This study collected samples with a sterile swab from the nasopharyngeal region, transported
them to the laboratory by a transport medium, and then cultured them on an agar culture medium. After
isolation, confirmatory tests and antibiotic susceptibility were performed. The results were analyzed
using SPSS16 software and interpreted according to Mann Whitney U and Chi-Square Tests.
Streptococcus pneumoniae was found in 15% of samples, and the antibiotic resistance of the isolates to
the antibiotics azithromycin, amoxicillin, rifampicin, amoxicillin-clavulanic acid,
trimethoprim/Sulfamethoxazole, and ceftriaxone were 63.9%, 56.6%, 41%, 37.3%, 37.3%, and 3.6%,
respectively. Also, 31.1% of the isolates were not resistant to any antibiotics. According to the results,
excessive use of antibiotics has led to high resistance to azithromycin, amoxicillin,
amoxicillin/clavulanic acid, and trimethoprim/Sulfamethoxazole, which indicates an increased risk of
refractory infectious diseases. For this reason, it is necessary to adequately educate physicians and the
general public about the overuse of antibiotics.

Published: July 2022

This research aimed to investigate the microbial spectrum of microorganisms that cause ventilatorassociated
pneumonia (VAP) among ICU patients in the selected hospital, antimicrobial susceptibility,
genetic diversity of common isolates, and the monitoring effect of microbial culture on cleaning and
sanitizing of external ventilator circuits in order to reduce the occurrence of hospital infections. For this
purpose, endotracheal aspirate (ETA) specimens were sampled from ICU patients with clinically
suspected VAP in the hospital between August 2020 and August 2021 and then investigated for
microbiological content. This was followed by Kirby-Bauer testing for determining drug sensitivity and
ERIC-PCR for genotyping. Afterward, microbial culture was performed on cleaned, sanitized and dried
ventilator external ventilator pipelines and those stored aseptically for 4 weeks to evaluate the cleaning
and disinfection effect and measure the bacterial content. Results showed that in the 64 confirmed VAP
cases, Klebsiella was the most frequently isolated organism, followed by P. aeruginosa and
Acinetobacter baumannii, while Candida is the most widely isolated fungus. The antimicrobial
susceptibility spectrum revealed that 40% of the isolates were multidrug-resistant (MDR). ERIC-PCR
showed no genetic relationship between pneumococcal isolates. Through microbial culture, no
pathogenic bacteria were detected among cleaned and sanitized ventilator external ventilator pipelines
and those stored aseptically for 4 weeks, indicating a 100% pass rate. It was concluded that ventilators
in intensive care units (ICU) are susceptible to contamination, exposing patients to bacterial
contamination and other comorbidities. Gram-negative bacteria are the main pathogens of VAP, which
are mostly multidrug-resistant. Clinical care measures for ventilators should be strengthened to reduce
the incidence of ventilator microbial contamination and to improve accurate clinical diagnosis and
correct antimicrobial therapy.

Published: July 2022

This experiment was conducted to investigate the effect of taking Baihe Gujin decoction combined with
Shengmai powder on IL-1β and IL-1Ra expression in peripheral blood CD14+ monocytes from patients
with pulmonary tuberculosis. For this purpose, one hundred adult patients with primary pulmonary
tuberculosis were selected for the study. The age of the enrolled cases ranged from 18 to 60 years old,
with a controlled male to the female sex ratio of about 1:1. The Chinese medical evidence was
considered to be a qi-yin deficiency type of pulmonary consumption. The patients were randomly
divided into experimental and control groups, 50 cases each. In addition, 50 cases of healthy people
were selected as a healthy control group, totaling 150 cases. In the experimental group, patients were
given Baihe gujin decoction and Shengmai powder based on conventional western medicine, 1 dose for
1 day, 150mL/time for 2 times. The control group was treated with conventional Western medicine. 2
mL of fasting elbow venous blood from the subjects was taken in the morning. Peripheral blood
mononuclear cells were isolated by density centrifugation. Monocytes were obtained after incubation
with 5 μL of CD14+ immune magnetic beads at 4°C. The relative expression of IL1β and IL1R genes
were measured using real-time quantitative PCR (RT-PCR), respectively. Results showed that the
relative expression of IL1β and IL1R genes was significantly lower in the experimental group after 3
months compared with the control group, and the statistical difference was highly significant (p<0.01).
It was concluded that the administration of Baihe gujin decoction and Shengmai powder was closely
related to the relative expression of IL1β and IL1R genes in patients' serum, indicating that Baihe gujin
decoction and Shengmai powder have an important role in improving the clinical symptoms of
pulmonary tuberculosis.

Authors: Ibrahim Hassan Ibrahim Hamed
Published: July 2022

The aim of current study was to investigate the relationship between strength and linear or non-linear sprint performance variables in U19 male field hockey players during the midseason time. Twenty eight players from Sharkia Hockey Club participated in current study with anthropometric data of mean±SD (age=17.57±1.23 years, height=1.71±0.05 meter, body weight=66.05±5.93 kg and body mass index=22.61±1.78 kg/m2). Participants were measured for lower limb strength (vertical height jump, power and standing long jump), liner sprint (sprint over 30meters with different short distance included) and non-linear sprint performance (L running and zigzag measures). The relationships between physical fitness qualities were assessed by Pearson product-moment correlation coefficient. There were a moderate relationship between VJ height and sprint 20m and 30m performances, (r=0.66 and 0.63), respectively. Likewise, similar moderate relationships observed between power and sprint 20m and 30m performances (r=0.62 and 0.61), respectively. In addition, no significant relationships observed with other sprint distances or change of direction measures when correlated to other variables of VJ and power results. The study concluded that, the knowledge of relationships between strength and cyclic or acyclic sprint performances at various distances would allow coaches to structure the field hockey training drills.

Authors: Saikia Hemanta , Bhattacharjee Dibyojyoti
Published: July 2022

Twenty20 format of cricket is a fast track ball game compared to the other formats of cricket viz. Test and One-day International (50-over a side). The Indian Premier League (IPL) is a national franchise based Twenty20 cricket tournament initiated by Board of Control for Cricket in India (BCCI). In this format, each batsman tries to score maximum runs in minimum balls. This fact increases the probability of dismissal of a batsman. As fall of wickets leads to the loss of resources of the batting side, thus it has an impact on the result of the game. This study tries to examine the survival ability of Indian and overseas batsmen in IPL 2012 season using a probabilistic model. The proposed model can be used to forecast the survival rate of the batsmen on the pitch in other format of cricket also, while the game is in progress. The findings of the study can be used to arrange the batting order of a team in Twenty20 cricket based on the match situation.

Authors: Marques Junior Nelson Kautzner
Published: July 2022

When the soccer player practices during the match the skills with emphasis on peripheral vision is important for he has a good vision of the players with the objective of the player practices a better action of the skill. The objective of the review was of present the peripheral vision training structure. The peripheral vision training the coach can prescribe during the technical training, the game situational training and the game training, but the ideal for each type of training the use of the motor learning practices. Therefore, the coach guides the athlete in all exercises when practicing the skill with the peripheral vision training through of the head up. After 15 sessions of indoor soccer, the offensive quality was detected in the peripheral vision training group (PG) and of the traditional training (TG). Two-way ANOVA detected a statistical difference (p≤0,05) between the PG versus the TG. The PG was better during the start of the attack and development of the attack than the TG. But the TG was better during the finalization of the attack (FA) of the 1st shift and the PG was better during the FA of the 2nd shift. The indoor soccer with less offensive actions causes more goals during the match. The PG practiced less action during the attack (2 to 4 actions of attack) and the TG practiced more actions during the attack (2 to 6 actions of attack). In conclusion, peripheral vision training is very important for the performance of the soccer player.

Adaptive Singular Evolutive Interpolated Kalman filter and its application to data assimilation in 2D Water pollution model
Authors: Ha Tran Thu , Son Hoang Hong , Phong Nguyen Hong
Published: July 2022

This study promotes a new algorithm for estimating the water pollution propagation with the primary goal of providing more reliable and high quality estimates to decision makers. To date, the widely used variational method suffers from the large computational burden which limits its application in practice. Moreover, this method, considering the initial state as a control variable, is very sensitive in specifying initial error, especially for unstable dynamical systems. The adaptive filter (AF), proposed in this paper, is aimed at overcoming these two drawbacks in the variational method: by its nature, the AF is sequential (no large batch assimilation window used) and stable even for unstable dynamics, with the gain parameters as control variables. The AF, developed in this paper, is an adaptive version of the Singular Evolutive Interpolated Kalman Filter (SEIKF). One of the new versions of this AF is that it uses a time-varying structure of the gain of SEIKF. To deal with the uncertainty of the system parameters and of the noise covariance, the proposed adaptive SEIKF (ASEIKF) makes use of the covariance of reduced rank iterated during assimilation process and of some pertinent gain parameters tuned adaptively to yield the minimum prediction error for the system output. The computational burden in implementation of the ASEIKF is reduced drastically due to applying the optimization tool known as a simultaneous perturbation stochastic approximation algorithm, which requires only two integrations of the numerical model. No iterative loop is required at each assimilation instant as usually happens with the standard gradient descent optimization algorithms. Data assimilation experiment, carried out by the SEIKF and ASEIKF, is implemented for the Thanh Nhan Lake in Hanoi and the performance comparison between the ASEIKF and SEIKF is given to show the high effectiveness of the proposed ASEIKF.

В настоящее время наблюдается дефицит отечественных исследований, посвящённых психологической собственности сотрудников (organization-based psychological ownership). Цель. Цель настоящего исследования — изучение соотношения психологической собственности и вовлечённости персонала в организацию с возможностью реализации мотивов, оценкой удовлетворённости организационной культурой, лояльностью, организационным гражданским поведением и намерением остаться в организации. Дизайн исследования. Выборку составили 106 работников российских организаций (без соотнесения с конкретными организациями), 65 женщин и 41 мужчина. Респондентам предлагалось заполнить следующие методики: опросник «Организационная лояльность» Л. Портера в адаптации В. И. Доминяка, опросник «Возможность реализации мотивов» В. И. Доминяка и Е. А. Родионовой, авторский инструмент для оценки вовлечённости в организацию, авторская анкета для оценки психологической собственности по отношению к организации, опросник «Шкала экстраролевого поведения» Б. Г. Ребзуева, опросник «Шкала ролевого поведения» Л. Вильямса и С. Андерсона, опросник «Инструмент для измерения организационной культуры» К. Камерона и Р. Куинна. Полученные данные были обработаны при помощи таких математико-статистических методов, как: корреляционный анализ с применением коэффициентов корреляции Пирсона и Спирмена, множественный регрессионный анализ, а также моделирование структурными уравнениями. Результаты. Результаты исследования показали, что существуют связи между изучаемыми нами переменными. Мы получили модель, согласно которой предиктором психологической собственности, вовлечённости и лояльности является возможность реализации мотивов профессиональной деятельности; психологическая собственность определяет лояльность и вовлечённость в организацию; вовлечённость определяет организационное гражданское поведение, а лояльность — намерение остаться в организации. Ценность полученных результатов. Полученная модель, как и освещение темы психологической собственности, составляет научную новизну данной работы.

Published: July 2022

В литературе по организационной психологии в последние десятилетия в связи с активным распространением идей позитивной психологии в организационном контексте возникли новые тенденции. Многочисленные исследования закладывают фундамент так называемой позитивной организационной доктрины, включая новые концепции — позитивного организационного поведения и позитивного организационного видения. Мнения учёных относительно статуса этих концепций разошлись. Одни убеждены в тождественности этих концепций, другие подчёркивают существенные различия между ними. Цель. Цель статьи — проанализировать разнообразные точки зрения на сходство и различия концепций, входящих в позитивное организационную доктрину, прояснить содержательные особенности каждой из них, найти основания для преодоления противоречий, возникших в дискурсе позитивной организационной психологии. Метод. Для достижения указанной цели использовался теоретический анализ литературных источников и систематизация результатов эмпирических исследований. Результаты. Рассмотрены исследовательские подходы в рамках позитивной организационной доктрины, выдвинутые Ф. Лютансом (концепция позитивного организационного поведения) и К. Камероном (концепция позитивного организационного видения). Несмотря на некоторые преимущественно «внешние» различия, этим двум концепциям присуще глубокое внутреннее сходство. Обе концепции возникли в начале 2000-х годов, выделившись из таких научных областей, как позитивная психология, организационное поведение, просоциальное организационное поведение и психология сообществ. Концепции сосредотачиваются на изучении процессов, которые позволяют развивать способности и позитивные качества сотрудника, обучать человека навыкам позитивного организационного поведения. Однако если позитивное организационное поведение исследует процессы на индивидуальном уровне, то позитивное организационное видение анализирует эти процессы преимущественно на организационном уровне. Это различие, в свою очередь, отражается и на использовании различных исследовательских методов. Ценность результатов. Выводы, полученные в ходе теоретического анализа позитивной организационной доктрины, дают обобщающую картину и расширяют наши представления о современном состоянии и об исследовательском потенциале концепций позитивного организационного поведения Ф. Лютанса и позитивного организационного видения К. Камерона.

В статье представлены результаты двух исследований, ставших первыми эмпирическими работами по изучению феномена страсти к делу в России. Целью исследования 1 была адаптация русскоязычной версии шкалы страсти к делу Р. Валлеранда. В исследовании приняли участие 659 взрослых респондентов со стажем профессиональной деятельности от нескольких дней до 48 лет. Результаты этого исследования показали, что русскоязычная версия шкалы страсти имеет двухфакторную структуру, соответствующую оригинальной версии шкалы и позволяющую диагностировать два типа страсти — гармоничную и одержимую. Обе субшкалы демонстрировали высокие показатели коэффициента α-Кронбаха, что подтверждает внутреннюю надёжность диагностического инструмента, а также предсказывали позитивный и негативный аффект, автономную и контролируемую профессиональную мотивацию, удовлетворённость работой и жизнью, что свидетельствует в пользу конвергентной и критериальной валидности адаптированной шкалы. Целью исследования 2 была апробация русскоязычной версии шкалы страсти за счёт изучения связей между страстью к делу и самооценкой здоровья у лиц, занимающихся зимним плаванием. В исследовании приняли участие 115 респондентов юношеского и взрослого возраста с опытом зимнего плавания от трёх месяцев до 56 лет. По результатам этого исследования было обнаружено, что гармоничная страсть является позитивным, а одержимая страсть — негативным предиктором самооценки физического, психологического и духовного здоровья. Кроме того, одержимая страсть негативно предсказывает психическое здоровье. Выводы. Проведённые исследования позволили сделать два основных вывода. Во-первых, русскоязычная версия шкалы страсти надёжна, валидна и может быть рекомендована для диагностики гармоничной и одержимой страсти у русскоязычных респондентов. Во-вторых, страсть к делу у людей, занимающихся зимним плаванием, частично предсказывает самооценку здоровья, что может быть использовано в диагностических и консультационных целях при работе с данной категорией.

В статье выполнен направленный обзор публикаций по психологии экстремального труда. Цель. Цель аналитического обзора — оценить перспективность и эвристичность исследования пространственно-временных ограничений, понимаемых здесь как субъективное восприятие специалистами пространственно-временных факторов в качестве негативных компонентов условий труда. Актуальность обращения к понятию, характеризующему субъективность восприятия условий труда, обосновывается тем, что в большинстве случаев в исследованиях не дифференцируются объективно и субъективно обусловленные особенности восприятия условий труда. Кроме того, соотношение условий труда и реакции человека на них изучается через совокупность факторов в качестве как зависимой, так и независимой переменной, без их дифференциации, либо дифференциация становится столь узкой, что теряет реалистичность. В обзоре характеризуются известные направления в психологии, в рамках которых изучаются пространственно-временные параметры условий труда, приводится совокупность характеристик вредных и опасных факторов, имеющих отношение к пространству и времени, определяющих экстремальность условий труда в Российском законодательстве, рассматриваются исследования, в которых пространственные и временные компоненты условий труда изучаются в качестве зависимых и независимых переменных, оценивается актуальность дифференцированного изучения субъективных факторов их восприятия и влияния на общее отношение специалистов к условиям труда. Выводы. На основании выполненного обзора делаются выводы о том, что в современном мире исследование процессов субъективного оценивания специалистами экстремального профиля пространственно-временных аспектов условий труда — весьма актуальная задача, требующая выявления достоверных признаков, причин и проявлений этих ограничений, которые могут использоваться в качестве критериев выхода за пределы индивидуально значимых границ нормы. Перспективы исследований в русле обозначенного направления оцениваются как эвристичные и приближающие результат к достоверности в реальной ситуации.

An Adaptive FLV Steganography Approach Using Simulated Annealing
Authors: Bawaneh Mohammed J. , Obeidat Atef , M.Al-kofahi Majd
Published: July 2022

Steganography is not only the art of hiding secret messages in cover media but also a process of communication and secure data transfer. Secret messages can be sent over the Internet with security by using several steganography techniques, but all of them present challenges in steganalysis. This study proposes a new secure technique called flash video (FLV) file steganography that keeps the frame video quality and is difficult to detect. The technique can hide any type of secret message inside a given FLV file. The secret message is divided into packets of the same length, reordered packet, and encrypted bytes before being hidden at the end of a selected video tag. A simulated annealing (SA) approach to select tags for steganography is presented to reduce or avoid the challenge of steganalysis. The proposed method uses SA as supporting framework to deal with the FLV file as a host for different types of secret messages. The system determines the minimum path within the host FLV file by using SA and hides the message bits inside each pixel in the minimum computed path. Analysis of the host FLV file cannot be performed without proper knowledge on the transformation process. Thus, the existence of the secret message is difficult to detect by steganalysis. Knowledge is represented by the key of finding the minimum path in the host FLV file, key of secret message length, key of additional bytes, key of message packets reordering and key of message extension. Experimental results show that the proposed technique satisfies the main requirements of steganography with regard to visual appearance, capacity, undetectability, and robustness against extraction.
Determination of Itinerary Planning for Multiple Agents in Wireless Sensor Networks
Authors: Rais Amine , BOURAGBA KHALID , Ouzzif Mohamed
Published: July 2022

The mobile agent is a new technology in wireless sensor networks that outperforms the traditional client/server architecture in terms of energy consumption, end to end delay and packet delivery ratio. Single mobile agent will not be efficient for large scale networks. Therefore, the use of multiple mobile agents will be an excellent solution to resolve the problem of the task duration especially for this kind of networks. The itinerary planning of mobile agents represents the main challenge to achieve the trade-off between energy consumption and end to end delay. In this article we present a new algorithm named Optimal Multi-Agents Itinerary Planning (OMIP). The source nodes are grouped into clusters and the sink sends a mobile agent to the cluster head of every cluster; which migrates between source nodes, collects and aggregates data before returning to the sink. The results of the simulations testify the efficiency of our algorithm against the existing algorithms of multi-agent itinerary planning. The performance gain is evident in terms of energy consumption, accumulated hop count and end to end delay of the tasks in the network.

Published: July 2022

Wireless Sensor Networks (WSNs) have become one of the most important components that play a major role in home environment applications. It plays a major role in the creation and the development of smart home environments. Smart homes creates home area network (HAN) to be used in different applications including smart grids. In this paper, we propose an enhancement to in-Home Energy Management (iHEM) scheme, namely EHEM, to reduce energy consumption by shifting the residents’ demands to mid-peak or off-peak periods depending on the appliances priorities and delays. The proposed system handles challenging cases by using internal storage battery. The performance of the proposed system is compared against iHEM and the traditional iHEM scheme, based on the total cost of the power consumption. Obtained results show slight improvement over the existing iHEM scheme

Wireless Local Area Network (WLAN) has been progressing rapidly. The IEEE 802.11n Physical (PHY) layer provides wider channel bandwidth, shorter guard interval, and up to four data streams. Therefore PHY 802.11n has a maximum of 128 data rate options from 6.5 Mbps to 600 Mbps. In addition, Medium Access Control (MAC) has been added Aggregate MAC Protocol Data Unit (AMDPU) scheme. If AMPDU is transmitted with a data rate corresponding to the channel conditions, then the probability AMPDU is received without error becomes increased. MAC determines the data rate used for transmitting AMPDU using a rate adaptation algorithm. Therefore some papers have proposed rate adaptation algorithms based on channel conditions. In this paper we propose a new rate adaptation algorithm that we call Adaptive Auto Rate Fallback for High Throughput (AARF-HT). Our development is done using NS-3 simulator version 3.26. AARF-HT algorithm performance is also tested through a number of simulations extensively. The simulation results show the data rate adaptation function based on the channel width, guard interval and the number of spatial streams in IEEE 802.11n WLAN has functioned well. The test results also show the AARF-HT algorithm resulted in higher throughput compared to the AARF algorithm.

In the last several years, many types of research are focusing on Vehicular Ad-hoc Networks (VANETs) field due to the lifesaving factor. VANETs are defined as a set of vehicles in the road interact with other vehicles or with the Road Side Unit (RSU) through wireless Local Area Network (WLAN) technologies. The fundamental advantages of VANETs are enhancing the road and driver's safety and improving the vehicle security against adversaries’ attacks. Security is the most difficult issue belonging to VANETs since messages are exchanged through open wireless environments. Especially in the authentication process, the vehicles need to be authenticated before accessing or sending messages through the network. Any violation of the authentication process will open the whole network for the attack. In this paper, we applied security algorithms to improve authentication in VANETs with four stages of cryptography techniques: challenge-response authentication, digital signature, timestamping, and encryption/decryption respectively. Also, we also proposed an algorithm model and framework. Finally, we implemented the challenge-response authentication technique, and then measured and evaluated the result from the implementation

Published: July 2022

Monitoring and analyzing network traffic are very crucial in discriminating the malicious attack. As the network traffic is becoming big, heterogeneous, and very fast, traffic analysis could be considered as big data analytic task. Recent research in big data analytic filed has produces several novel large-scale data processing systems. However, there is a need for a comprehensive data processing system to extract valuable insights from network traffic big data and learn the normal and attack network situations. This paper proposes a novel evolving fuzzy system to discriminate anomalies by inspecting the network traffic. After capturing traffic data, the system analyzes it to establish a model of normal network situation. The normal situation is a time series data of an ordered sequence of traffic information variable values at equally spaced time intervals. The performance has been analyzed by carrying out several experiments on real-world traffic dataset and under extreme difficult situation of high-speed networks. The results have proved the appropriateness of time series evolving fuzzy engine for network classification.

Published: July 2022

In multiple users MIMO- OFDM system allocates the available resources to the optimal users is a difficult task. Hence the scheduling and resource allocation become the major problem in the wireless network mainly in case of multiple input and multiple output method that has to be made efficient. There is various method introduced to give an optimal solution to the problem yet it has many drawbacks. So we propose this paper to provide an efficient solution for resource allocation in terms of delay and also added some more features such as high throughout, energy efficient and fairness. To make optimal resource allocation we introduce optimization algorithm named spider monkey with an enhancement which provides the efficient solution. In this optimization process includes the scheduling and resource allocation, the SNR values, channel state information (CSI) from the base station. To make more efficient finally we perform enhanced spider - monkey algorithm hence the resource allocation is performed based on QoS requirements. Thus the simulation results in our paper show high efficiency when compared with other schedulers and techniques.

Published: July 2022

Vehicles engine failure is disapproved problem for drivers, and repair of that needs experience to identify fault and troubleshooting. The fault diagnosis in a machine is significant for fending off dangerous damage. The vibration signals of a machine always carry the dynamic information of the machine. These vibration signals of internal combustion engines are extremely helpful for the feature extraction and detect the fault diagnosis. The former sensing of defects by supervising can keep farther harm to the internal combustion engine and deflect further causalities. The faults lead to reducing the engine performance and increasing the harmful pollution. In this paper, present techniques of a denoising method for vibration signal analysis that had been proposed such as fast Fourier transform (STFT), higher-order statistics (HOS), Wigner–Ville distribution (WVD), and wavelet transform (WT) and adaptive order-tracking.
