The compaction forming of metal powder is a process involving large deformations, large strain, non-linear material behavior and friction. Consequently, the numerical analysis of such a highly non-linear process is a formidable computational problem. In this paper, an ALE technique is presented based on a generalized cap plasticity model in simulation of powder forming processes. In ALE formula...

BACKGROUND Asystasia gangentica (A. gangetica) belongs to the family Acanthaceae. It is used to treat hypertension, rheumatism, asthma, diabetes mellitus, and as an anthelmintic in South Africa, India, Cameroun, Nigeria, and Kenya respectively. It has also been reported to inhibit the angiotensin I converting enzyme (ACE) in-vitro. Therefore, the aim of this study is to investigate the in-vivo ...

Současné trendy v oblasti ukotvování symbolů pomocí senzorických modalit se ukazují jako přínosné, ale narážejí na omezení, plynoucí z ukotvování na základě asociace symboly s perceptuálními kategoriemi bez hlubší analýzy problému. Članek se zabývá zabývá analýzou některých východisek formální sémantiky a následně přehledem výzkumů ukotvení s poukazem na jejich slabá místa. Obsahuje také popis ...

Evaluating the performance of long-term care (LTC) demonstrations requires longitudinal assessment of multiple outcomes where selective mortality and disenrollment, if not accounted for, can give the appearance of reduced (or enhanced) efficacy. We assessed outcomes in social/health maintenance organizations (S/HMOs) and Medicare fee-for-service (FFS) care using a multivariate model to estimate...

This paper provides onvergen e analysis for maximum likelihood estimation of the parameters des ribing a parti ular multi-s ale pro ess known as fra tional Brownian motion. We on entrate on s hemes that `pre-whiten' the available noise orrupted data via the Fast Wavelet Transform and show that su h s hemes are strongly onsistent and asymptoti ally eÆ ient. We also analyse the rate of onvergen e...

In this paper, we propose a new Authenticated Lightweight Encryption algorithm coined ALE. The basic operation of ALE is the AES round transformation and the AES-128 key schedule. ALE is an online single-pass authenticated encryption algorithm that supports optional associated data. Its security relies on using nonces. We provide an optimized low-area implementation of ALE in ASIC hardware and ...

On a growing scale, we use mobile phones for diverse activities in our daily life, for example for entertainment, information or education purposes. In our present research, we assess the feasibility of using a mobile phone to unobtrusively track its user physical activity and the resulting energy expenditure; without of use of any dedicated external device. Activity Level Estimator (ALE) is an...
