There are several possible methods through which attackers can attack a server. Distributed denials of service (DDoS) attacks are one of these attacks types in computing environments. In this paper, we discuss the possible ways of DDoS attacks detection using artificial neural network based techniques. Here a feed forward neural network is designed to detect DDoS attacks in a network based environment. Performance of feed forward neural network is analyzed by applying three different training algorithms. These algorithms are (1) Scaled Conjugate Gradient (2) Bayesian Regularization and (3) Gradient Descent. Results show that Bayesian Regularization algorithm is better among these three training algorithms and it has less number of misclassifications.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"13 1","pages":"671-676"},"PeriodicalIF":0.0,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77196254","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 traditional veterinary healers are therefore getting more attention from farmers. Thirty mastitic goats were selected and divided into five equal groups viz; A, B1, B2, C1 and C2. Groups were treated as A: control (no treatment), B1: parental injections of amoxicillin with clavulanic acid and flunixinmaglumine, B2: trimethoprim with sulphadiazene and flunixinmaglumine, C1: oral treatment of Garlic (Allium Sativium L.) and Turmeric (Curcuma Longa L.), C2: Purple fleabane (Centratherum Anthelmenticum) and Turmeric (Curcuma Longa L.). The bacterial load of clinical mastitis before and after treatment was measured. The bacterial load was noticed significantly reduced in group B, followed by C compared with A at 7th and 14th day of conventional and traditional treatments respectively. Furthermore, on day 28th of trial the right teat bacterial load was significantly reduced in all treated groups vs control. Out of 1260 milk samples, the clinical and subclinical mastitis was observed in 65 (5.15%) and 226 (23.1 %) animals respectively. The temperature, pulse, respiration, udder circumference and cumulative bacterial load were elevated in untreated animals and on 0 day, which further subsides following treatment in different groups. The milk quantity was seriously reduced in mastitic goats, however some of the lost milk quantity was recovered following different treatments. It has been revealed that the medicinal plants can also be used effectively at very low cost but recovery is slow.","PeriodicalId":21859,"journal":{"name":"Sindh University Research Journal","volume":"38 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82684364","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}

Furthermore, quality of public transport service as per consumers’ desires is an important issue nowadays. This study aims to assess the citizen’s perceived satisfaction regarding the quality of Paratransit public transport as well as to provide guidelines in order to improve the conditions of transportation system.

The present study was conducted to fill this gap and robust the existing process of implementation of PI in IT projects. Field survey was conducted using 5 likert scale questionnaire, based on extracted critical success factors. In order to collect the data, Purposive sampling was used along Delphi technique. 6 out of 10 experts responded in each subsequent round. Data was analyzed in SPSS. Statistical analysis showed the consensus of experts on 10 CSF’s which played an important role for the successful implementation of PI in IT projects.

One possible reason for these situations is that proper risk management techniques are not applied during the planning and execution of projects. This paper introduces a method which uses the impacts of risk in project scheduling. A simple infrastructure project is considered for analysis. Uncertainty in activity durations is assigned using various statistical distributions. Further, certain risk events are added to the project using risk register. The impact of these uncertainties in activity durations and risk events are modeled and simulated in @Risk software. The software uses Monte Carlo simulations for risk analysis. The results show that the model can predict the impact of uncertainty in activity durations on the pro-ject completion time.
