In virtualized shared environment, the availability of the shared resources for the shared multiple clusters/Virtual Machines is always matters. To provide the better performance to the end users of the cloud VMs and for the always availability of shared resources, virtual machine migration is always a challenging task in virtualized environment. The aim of this research is to investigate various parameters of live data migration between the shared clusters/virtual machines in state-full context and overall load balance level. The proposed migration strategy ensures the avoidance of attacks/anomalies which causes the load increase on the VMs which effects the entire system. This could be done by the resource allocation from one cluster to another via checkpointing method of VM to maintain the state of the VM, load of the VM including resource availability. Using Xen hypervisor memory technique which dynamically allows the migration of the configured memory while the allocated memory could be discarded for a while. By this the bad memory remains un-migrated only the good memory consisting the used data would be migrated by means of Real-time.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"4 1","pages":"107-114"},"PeriodicalIF":0.0,"publicationDate":"2018-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84796456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The radiating patch is made up of copper material backed by a 0.254 mm thicker Roggers-5880 substrate (N9000 PTFE) having relative permittivity and loss tangent of 22x10-1 and 9x10-4, correspondingly. The antenna resonates at 23 GHz frequency band. The major lobe gain of the single component 5G antenna is 7.16 dB.To meet the gain requirements of 5G mobile communication systems, 1 x 4 element array antenna has been proposed which increases the bore side gain up to 12.6 dB at the desired frequency. The proposed antennas efficiency is 91-94 % with a sufficient amount of driving point impedance bandwidth (S11<- 10 dB), i.e. 600-620 MHz;The SAR of the proposed antenna is analyzed at two different parts of human body, i.e. belly and hand. The SAR is averaged over 10g of tissue. The proposed 1 x 4 element antenna gives lower values of SAR (<2 W/kg) on all parts of human body. The proposed array antenna can be used in 5G mobile handheld devices. All the simulations are carried out using CST MWS. The proposed antenna is suitable contender for 5G mobile communication systems.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"25 1","pages":"27-32"},"PeriodicalIF":0.0,"publicationDate":"2018-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88405601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus a tetrad is formed if four guanines are attached with each other. These tetrads are the cause of the formation of unusual structures called G-quadruplex structures. These structures not only formed by a single guanine rich nucleic acid sequence but their formation is also possible by two or four parallel sequences collectively. These structures (or guanine rich sequences through which they are formed) affect a well known technology named Affymetrix GeneChip which is popular for gene expression measurement effectively and cheaply. Since the nucleic acid sequences are placed very closely on GeneChip, they are able to interact with each other and then form G-quadruplex structures. In this case, they are not ready to hybridize with their target sequences. It is found that raw or hybridization level data of human, mouse and rat (mammalian in general) are affected by guanine rich sequences. This paper exhibits that GeneChips of two Bacterias are also affected by guanine-guanine interaction and hence measurement of gene expressions using these chips could be misleading.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"68 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2018-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89296052","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Stories, newspapers are the page collection that belongs to text categorization. Various Sindhi newspapers are regularly published and Daily Kawish is one of them. People are facing difficulties during reading newspaper because there is no any specific option that will categorize particular news related to sports, technologies, crime, fashion and current affairs. For this purpose, a Text Categorization System (TCS) for Sindhi language is presented in this paper. Five classes are used and scanned each newspaper page inside a single class. It is too difficult to predict how many users will read newspaper simultaneously and for this, web performance is tested. Moreover, for the classification of the text from pages, precision, recall and f-measure are used to measure and achieved 67% of accuracy to classify the text from newspaper pages. It would be beneficial for those who want to save their precious time during reading newspaper.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"23 1","pages":"85-90"},"PeriodicalIF":0.0,"publicationDate":"2018-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73977596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
