Academic work, in addition to other factors, depends on the school environment, teacher behavior and family support. The current study is important because it has studied the impact of stress on students' performance. The study aimed at investigating the influence of stress on student’s performance. The study was created in high schools located in the Vehari district of Punjab, Pakistan. The sample consisted of 10 secondary schools in Vehari district. The choice of secondary schools (5 male schools and 5 female schools) was followed by a simple random sampling method. A survey was conducted to find out the impact of stress on student performance. Three independent educational psychology experts have approved the instrument. Using the statistical package, the researcher analyzed the data obtained. The study recommends that: (i) teachers should be able to provide instruction using good teaching metho...

Analysts have find out serious security flaws and vulnerabilities in most widely used MD and SHA family hash functions. As a result hash functions from FORK family with longer digest value were considered as good alternatives for MD5 and SHA-1, but recent attacks against these hash functions have highlighted their weaknesses. In this paper we propose a dedicated hash function HMACMD5= MD5 (HMAC (K,m))//32 BIT based on the design principle of HMAC and MD5. It takes 512 bit message blocks and generates 32 bit hash value. A random sequence is added as an additional input to the compression function of HMACMD5. Three branch parallel structure and secure compression function make HMACMD5 an efficient, fast and se...

The important motives of this study are to explore the stress impact on the students' academic performance. Stress has a key role in student's academic performance. This study was to focus on the negative impact on the student's academic performance. The purposes of the study were to investigate; firstly, the type of stress linked with student's performance; secondly, to evaluate the impact of stress on the academic performances of students; and thirdly, differentiate the impacts of stress on the academic performances of both gender students. To achieve the above-mentioned objectives of the study, the researcher can suggest a reasonable solution for the impact of stress on student's academic performance. The data collected for this topic, has been gathered from all the secondary schools in District Vehari. In this study the researcher was taken a sample of (n=10) secondary schools from each Tehsil of District Vehari. The researcher was further divided (n=10) secondary schools into two groups (n=5) males and (n=5) female secondary schools. The researcher was taken (n=15) students from each secondary school selected as sample. The researcher was used simple random sampling technique for data collection. Five points Likert-scale used in this research.
