Sandblasting is traditionally known as a high-risk profession for potential development of lung silicosis. Reported is a case of a sandblaster with confirmed accelerated silicosis, a condition rather rarely diagnosed in the Czech Republic. Initially, the patient presented with progressive dry cough and exertional dyspnoea. In the early diagnostic process, a possible occupational aetiology was c...

Recent work in unsupervised feature learning and deep learning has shown that being able to train large models can dramatically improve performance. In this paper, we consider the problem of training a deep network with billions of parameters using tens of thousands of CPU cores. We have developed a software framework called DistBelief that can utilize computing clusters with thousands of machi...

Compilers for Digital Signal Processors (DSP) have been inefficient. The constraints have been two-fold. First, signal processing algorithms that use non-associative arithmetic are not easily described in high-level languages such as C, C++, and Java. Second, historical DSP architectures have been difficult compiler targets due to their non-orthogonal instruction sets. With modern DSP architect...

General-purpose processors have utilized complex and energy inefficient techniques to accelerate performance. In embedded DSP designs, power constraints have precluded general-purpose microarchitectural techniques. Rather than minimize average execution time, embedded DSP processors require the worst-case execution time to be minimized. Subsequently, Very Long Instruction Word (VLIW) processors...

Silicosis is considered to be among the occupational lung diseases and associated with sandblasting, mining, quarrying and tunneling. Acute silicosis is usually progressive diseaseand despite treatment with corticosteroids it leads to cardio-respiratory failure and death. Alveolar silicoproteinosis is one of it's acute presentations due to exposure to silica dust and lungs filling with proteina...

Evolving 3G standards such as TD-SCDMA use multi-user detection (MUD) at the base station to enhance the link bugdet in the uplink. Several sub-optimal block-based techniques have been proposed for detecting the user signals in multipath. These methods have been prohibitively expensive for implementation at the mobile. In this paper, we examine some of the most promising algorithms and consider...
