Social engineering has emerged as a serious threat in virtual communities and is an effective means to attack information systems. The services used by today’s knowledge workers prepare the ground for sophisticated social engineering attacks. The growing trend towards BYOD (bring your own device) policies and the use of online communication and collaboration tools in private and business enviro...

Cloud computing is a significant alternative in today’s educational perspective. The technology gives the students and teachers the opportunity to quickly access various application platforms and resources through the web pages on-demand. Unfortunately, not all educational institutions often have an ability to take full advantages of the newest information technology. The paper analyzes possibi...

In this work, we present the Text Conditioned Auxiliary Classifier Generative Adversarial Network, (TAC-GAN) a text to image Generative Adversarial Network (GAN) for synthesizing images from their text descriptions. Former approaches have tried to condition the generative process on the textual data; but allying it to the usage of class information, known to diversify the generated samples and ...

This paper presents an experimental evaluation of the performance costs of a wide variety of authentication methods over IKEv2 in wireless networks. The studied methods are preshared keys (PSK), extensible authentication protocol (EAP) using MD5, SIM, TTLS-MD5, TLS, and PEAP-MSCHAPv2. For the EAP-based methods RADIUS is used as authentication, authorization, and accounting (AAA) server. Two net...

We propose testing for business cycle first-moment asymmetries in Markov-switching autoregressive (MS-AR) models. We derive the parametric restrictions on MS-AR models that rule out types of asymmetries such as deepness, steepness, and sharpness, and set out a testing procedure based on Wald statistics which have standard asymptotics. For a two-regime model, such as that popularised by Hamilton...

a quantitative analysis method for fudosteine in human serum by high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (hplc-esi/ms/ms) was established, which shows high sensitivity and selectivity. the mobile phase composition was 75% 20 mm acetic acid and 25% acetonitril, which was pumped at a flow rate of 0.40 ml/min. the overall chromatographic run time was ...

The data provide information in support of the research article, "The cleavage specificity of the aspartic protease of cocoa beans involved in the generation of the cocoa-specific aroma precursors" (Janek et al., 2016) [1]. Three different protein substrates were partially digested with the aspartic protease isolated from cocoa beans and commercial pepsin, respectively. The obtained peptide fra...
