Abstract:
With the rapid development of wireless systems, the demand for frequency resources has been increasing in recent years. Therefore, it is necessary to consider the high-quality communication method that efficiently utilizes finite frequency resources. In this paper, Single Sideband 16 Pulse Amplitude Modulation (SSB 16PAM) scheme for the uplink communication is proposed. It transmits data in only Lower Sideband (LSB) without extra Hilbert components. Under Additive White Gaussian Noise (AWGN) channel environment, Bit Error Rate (BER) performance of the proposed scheme is superior by 3 dB in terms of Carrier-to-Noise Ratio (CNR) to 256 Quadrature Amplitude Modulation (256QAM) scheme with the same frequency efficiency and the same Peak-to-Average Power Ratio (PAPR). Our proposed scheme employs the original frequency domain filter on the transmitter side to form an ideal spectrum. The configuration of its process is almost similar to Single Carrier-Frequency Division Multiple Access (SC-FDMA), moreover, half of the input data on the frequency domain is removed. The proposed frequency domain filter produces the SSBmodulated spectrum with a roll-off rate of zero without degrading the BER performance.

Abstract:
The problem of non-fragile dynamic output feedback H∞ control for a class of uncertain switched systems with time-varying delay is discussed. Firstly, the form of non-fragile dynamic output feedback H∞ controller is given. Under the condition that the upper bound of time delay and the upper bound of delay derivative are limited simultaneously, Lyapunov functional and its corresponding switching rules are constructed by using single Lyapunov function method and convex combination technique; Secondly, we use the inequality lemma to scale the derived Lyapunov functional in order to eliminate the time-varying delay term in the inequality, and then introduce the J-function to obtain a nonlinear matrix inequality that satisfies the H∞ performance index γ, we also employ Schur complement lemma to transform the nonlinear matrix inequality into set of linear matrix inequalities consisting of two linear matrix inequalities, a sufficient condition for the existence of a non-fragile dynamic output feedback H∞ controller and satisfying the H∞ performance index γ is concluded for a class of uncertain switching systems with variable time delay; Finally, a switched system composed of two subsystems is considered and the effectiveness and practicability of the theorem are illustrated by numerical simulation with LMI toolbox.

Abstract:
M-Sequences play a big important role, as the other binary orthogonalsequences, for collection the information on the input links and distributionthese information on the output links of the communication channelsand for building new systems with more complexity, larger period, andsecurity, through multiplication these sequences. In our article we try tostudy the construction of the multiplication sequence {zn}and its linearequivalent, this multiplication sequence is as multiple two sequences, thefirst sequence{an}is an arbitrary M-sequence and the second sequence{bn}is not completely different but is the reciprocal sequence of the firstsequence {an} that is the reciprocal sequence has characteristic polynomialg(x) is reciprocal of f(x), which is the characteristic polynomial of the firstsequence {an}, also we will study the linear equivalent of the multiplicationsequence {zn}and we will see that the length of the linear equivalent of {zn}is equal to ((deg f(x))2 - deg(f(x)).

Abstract:
This paper presents a First responder emergency response tool (EMApp) as a step towards achieving integrated emergency care in developing countries, the case of Uganda. The EMApp prototype has potential to support health emergency response from various emergency stakeholders. This innovation is in line with strategic plans to embrace technologies towards the establishment of integrated social services such as emergency healthcare services (EHS) in Uganda. We describe the prototype and provide its functionalities that can be further enhanced to enable access to emergency services and save life. The possible assumptions, potential challenges and recommendations to implement and deployment of such a system are provided. There is currently no such integrated emergency response system in Uganda as is the case in many other developing countries. For future studies, there is need to deploy the tool and assess its impact on the communities.

Abstract:
Our goal is to develop THz module on chip to visualize bone grinding atthe early stage so that arthritis can be visualized and treated early. A criticalcomponent of such module is antenna. A compact 4 by 4 beamformingantenna array for biomedical application is presented in this paper. Weare proposing a novel antenna which is in the form of a circular ribbonshape with a gold patch. Gold material for the patch is used to enhance itsconductivity and to cut down backward radiation. Differential port pin usedto increase the bandwidth. Au-posts are finally used for output connection.The proposed antenna operates over the frequency band from 201 GHz tomore than 228 GHz. Directivity and gain of the proposed antenna are 13dB and 7 dB respectively. This makes it applicable for imaging systemsbecause of the frequency band for biomedical imaging.

Abstract:
A novel architecture for Wireless Power Transfer (WPT) module usingmonolithic components on GaN is presented in this paper. The design ofsuch a WPT module receives DC power from solar panels, consists ofphotonic power converter (PPC), beamforming antenna, low pass filter,input matching network, rectifier, output matching network and logic circuit(off-chip) which are all integrated on a GaN chip. Our WPT componentsshow excellent simulated performance, for example, our novel beamforming antenna and multiple port wideband antenna have a gain of 8.7 dBand 7.3 dB respectively. We have added a band pass filter to the rectifieroutput which gives two benefits to the circuit. The first one is filteringcircuit will remove unwanted harmonics before collecting DC power andsecond is filter will boost the efficiency of rectifier by optimizing the loadimpedance. Our proposed rectifier has RF-DC conversion efficiency of74% and 67% with beam-forming antenna and multiple port wide bandantenna respectively. Our WPT module is designed to charge a rechargeablebattery (3 V and 1 mA) of a radio module which will be used between twoantennas in future 5G networks. We believe our proposed WPT modulearchitecture is unique and it is applicable to both microwave and millimeterwave systems such as 6G.

Abstract:
MatBase is a prototype data and knowledge base management expert intelligent system based on the Relational, Entity-Relationship, and (Elementary) Mathematical Data Models. Dyadic relationships are quite common in data modeling. Besides their relational-type constraints, they often exhibit mathematical properties that are not covered by the Relational Data Model. This paper presents and discusses the MatBase algorithm that assists database designers in discovering all non-relational constraints associated to them, as well as its algorithm for enforcing them, thus providing a significantly higher degree of data quality.

Abstract:
Due to the rapid development of society, public places, especially large shopping malls, are relatively frequent places for emergencies. Such emergencies not only seriously affect public security and property, but also bring great psychological pressure to citizens. Therefore, this study is of great significance for the exploration and study of public place emergencies.The research object of this study is the public shopping mall. Based on the AnyLogic simulation platform and guided by the relevant principles of social force model, this study utilize the pedestrian storehouse in the platform as the core module to build the simulation environment, and attempts to simulate the police force restraining effect on the overall event and the perpetrators after the occur of emergent incident under different police force allocations. In order to ensure the accuracy of the experimental data, the research team conducted field survey to estimate the average flow of people and the general data of the security personnel in shopping malls, also estimated the restrain and capture time after repeated experiments.The results indicate that increasing additional police force outside the shopping malls and pre-organizing reasonable patrol routes can obviously facilitate police officers to restrain perpetrators. Meanwhile, it is also clear that the Anylogic platform can effectively simulate pedestrian movement and interaction behaviour in emergencies.
