Philips recently released a new VCSEL and photodiode product family for the fast growing FDR InfiniBandTM generation. In this work we review the influence of production process variations on VCSEL characteristics, the FDR VCSEL transmission behavior as well as wear-out reliability characteristics. Data collected during an initial 15 wafers pilot production batch verify that FDR VCSEL manufactur...

In Philips there is a need for many competent software developers. Not for everyone in the company software development is a real engineering activity. They claim that there are no fundamental theories underlying software and software construction. On the other hand, only a few universities offer a curriculum in software engineering, most curricula deal with computer science. Since ten years we...

Should we correct our students’ language errors? Most ESL teachers would answer this question with a resounding Yes while at the same time wondering how to meet the challenge. The collaborative project reported below was designed to provide ESL teacher trainees with an opportunity to experience the ups and downs of providing corrective feedback on writing and develop their awareness in this reg...

Increasing climate variability and extreme weather conditions along with declining trends in both rainfall and temperature represent major risk factors affecting agricultural production and food security in many regions of the world. The rangelands of Ethiopia, Kenya, and Somalia in the East African Horn remain one of the world’s most food insecure regions, yet have substantially increasing hum...

A two-month-old male infant presented with cardiac heart failure. Two-dimensional (2D) echocardiography showed an anomaly of the left coronary artery (LCA) arising from the pulmonary artery (Fig. 1) with mitral regurgitation (Fig. 2). Three-dimensional (3D) echocardiography was performed to determine left ventricular (LV) volume (i.e., 33, paediatric matrix probe 2—7MHz, Philips). The global an...

This paper addresses the almost never-ending headache the role of documentation has given for software projects. Working software has been given recently a focus over comprehensive documentation, yet the required documents should be authored. This paper “revisits” the approach developed by Nokia improving the documentation work without scarifying the quantity or quality of documentation. The me...

The spatio-temporal variability of trends in vegetation greenness in dryland areas is a well-documented phenomenon in remote sensing studies at global to regional scales. The underlying causes differ, however, and are often not well understood. Here, we analyzed the trends in vegetation greenness for a semi-arid area in northeastern Brazil (NEB) and examined the relationships between those dyna...

Two-point boundary value problems for two-dimensional systems of linear differential equations with singular coefficients are considered. The cases are optimally described when the above-mentioned problems have the Fredholm property, and unimprovable in a certain sense conditions are established guaranteeing the unique solvability of those problems. îâäæñéâ. àŽêýæèñèæŽ ëîûâîðæèëãŽêæ ïŽïŽäôãîë Ž...
