However it differs from T. malabaricus sp. nov. in having the following characters, vertex granulate anteriorly, rugose posteriorly, middle lobe of mesoscutum with a weak median longitudinal ridge (vertex granulate; middle lobe of mesoscutum with moderately developed medial longitudinal ridge in T. malabaricus sp. nov.), mesopleuron rugose-striate, moderately setose except postero-ventrally glabrous (mesopleuron rugose, moderately setose antero-dorsally, punctate and setose antero-ventrally, smooth, shiny and setose posteriorly except around pleural sulcus glabrous in T. malabaricus sp. nov.), sixth metasomal tergite with small angular protuberences posterolaterally (sixth metasomal tergite slightly rounded postero-laterally in T. malabaricus sp. nov.), medial emargination of sixth metasomal tergite 0.80× as long as tergite medially (medial emargination of sixth metasomal tergite 0.64× as long as tergite medially in T. malabaricus sp. nov.).Published as part of Sheeba, M., Ranjith, A.

SHEEBA: A spatial high energy electron beam analyzer
No full textElectron bunches with large energy and angle spread are not easy to be analyzed with conventional spectrometers. In this article, a device for the detection of high energy electrons is presented. This detector, based on the traces left by electrons on a stack of dosimetric films, together with an original numerical algorithm for traces deconvolution, is able to characterize both angularly and spectrally (up to some mega-electron-volts) a broad-spectrum electron bunch. A numerical test was successfully performed with a virtual electron beam, which was in turn reconstructed using a Montecarlo code (based on the CERN library GEANT4). Due to its simplicity and small size, the spatial high energy electron beam analyzer (SHEEBA) detector is particularly suitable to be used in laser plasma acceleration experiments. © 2005 American Institute of Physics

Comparative analysis of facial expression recognition system for age, gender, and emotions
No full textFacial expression recognition systems have advanced quickly, allowing for accurate real-time detection of age, gender, and emotion. Facial features are retrieved effectively for exact identification using deep learning models such as MobileNetV2, ResNet, and DenseNet, as well as approaches like the Haar cascade classifier. The use of datasets such as FER 2013 promotes robust model training, while preprocessing procedures provide peak performance. Models such as the Caffe model achieve great accuracy in detecting age and gender in real time through transfer learning and fine-tuning. These improvements highlight the potential of facial recognition systems in a variety of applications, including enhanced security, healthcare, and human-computer interaction

Enterprise application integration can be defined as a set of technologies and the use of software to integrate applications. This project uses open standards and the principles of Service-Oriented Architecture (SOA) to demonstrate application integration.\ud
Applications in an enterprise are designed to work in silos. Each application provides capabilities and functions to satisfy specific requirements. But, the information within an enterprise needs to be made available across these silos???? hence the need for loosely coupled, less invasive integration strategies. This project demonstrates how SOA can be used to integrate two disparate applications.\ud
The project consists of two applications: a Contact Management system (CMS), which is a Web application developed in J2EE, and a Contact Client (CC)\ud
vii\ud
application developed using Java Swing. The CMS system manages contact information of an enterprise. This system also provides services as Web services that applications can use to retrieve and create contact information. The client application uses these Web services to retrieve a contact by a unique contact identifier and to create new contacts.CSU, Chic
