This paper presents a 15-bit successive approximation register (SAR) ADC for using in biomedical processing systems. The segmentation degrees (the amount of bits in each divided capacitive sub-array) are optimized to minimize switching power and area based on linearity and matching requirements.

Systemically acquired resistance (SAR) and Induced systemic resistance (ISR) agents can trigger host system to produce phenolic compounds, PR proteins, sugars which impart resistance in plants against invading pathogens. The application of different concentrations of salicylic acid and Trichoderma viride (Tri-25) viz., single inoculation, combination inoculation with challenge inoculation of Exserohilum turcicum on the enhancement of growth and management of disease with special emphasis to ISR and SAR against turcicum leaf blight disease.

Thiazolidinedione is a pentacyclic moiety having five membered unsaturated ring system composed with carbon, oxygen, nitrogen and sulfur molecules at 1 and 3 position of the thiazole ring and widely found throughout nature in various form. They favourably alter concentration of the hormones secreted by adipocytes, particularly adiponectin.

The increased demand for higher resolution and detailed SAR imaging builds up a pressure on the processing power of the existing systems for real time or near real time processing. Exploitation of GPU processing power could suffice the increasing demands in processing. The processing of initial SAR systems was based on the principles of Fourier Optics.

These SAR achievements with virus diseases in tobacco, papaya, chilli, potato and cucumber mean that promising results can be expected if SAR method is applied to RGSD and RRSD in rice. If successful, we can introduce this method to help farmers limit damage when they cannot avoid BPH at the beginning of crop. To reach this aim, the study was conducted in the net-house to find the best effective chemicals in SAR to RGSD if the rice plants were infected early, at 7 days after sowing.

The difference of the chaetotaxy on three endites of maxillula and the difference of length of posterior tooth of left valve’s hingement were consistent with three phylogenetic groups. The total number of setae of three endites on the maxillula was lowest in the Group A, highest in the Group C, but the length of posterior tooth in hingement of the left valve was largest in the Group A and smallest in the Group C.

In this paper, we present a method for the semantic tagging of word chunks extracted from a written transcription of conversations. This work is part of an ongoing project for an information extraction system in the field of maritime Search And Rescue (SAR). Our purpose is to automatically annotate parts of texts with concepts from a SAR ontology. Our approach combines two knowledge sources a SAR ontology and the Wordsmyth dictionarythesaurus, and it uses a similarity measure for the classification.

The financial sectors in South Asia Region (SAR) are dominated by commercial banks, which account for the vast majority of the financial system s assets. The domestic debt markets including the government bond and corporate bond markets are at an early stage of development and there are few institutional investors. In recent years, countries in SAR have attempted to develop local debt markets, although the pace of development remains uneven and slow due to many regulatory and institutional impediments....

The invariable motif for analog design is to explore the new circuit topologies, architectures and CAD technologies to overcome the design challenges coming from the new applications and new fabrication technologies. In this book, a new architecture for a SAR ADC is proposed to eliminate the process mismatches and minimize the errors.

Farming of groupers (members of the Serranidae, subfamily Epinephelinae) is widely practised in Asia, particularly in the tropical East (China, Hong Kong SAR, Taiwan Province of China) and Southeast Asia (Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam). Most grouper species bring high prices in local or export markets, and thus are an attractive culture proposition for coastal aquaculture farmers.

A final reason apart from sharing in such economic growth and higher expected returns is the additional diversification benefits that may accrue. Studies have shown the considerable benefits to be gained from the international diversification in real estate markets (see Lizerli et al 1998 for a review).

Because the SAR-SF form is not tailored to the insurance industry, analysts for this study used the narratives to attempt to identify the exact reason for each filing. Us- ing the list of characterizations of suspicious activities in the proposed dedicated SAR form for insurance companies as a reference, analysts divided the filings into categories for statistical purposes. Table 11 includes a breakdown of the reasons derived from information in the narratives for the 641 filings.

The nature of annuities and their potential to be considered both insurance and in- vestment products complicated attempts during this study to differentiate annuities sold by insurance companies as insurance products from those annuities that qualify solely as investment products that happened to be sold by insurance companies. The SAR narratives reference annuities in the manner portrayed in Table 7.

First, this data does not compare directly with the occupational data derived solely from Field 7 (“Occupation or Type of Business”) on the SAR form. Filers sometimes leave Field 7 blank. Filers also sometimes provide information in narratives that is different from the information they provided in Field 7. Second, the subject(s) for the purposes of these statistics are not necessarily the subject(s) whose information appears in Part I of either the SAR-DI or SAR-SF.

Individuals accounted for the majority of listed subjects in the SARs; however, filers noted a few as business entities and, in some cases, identified a family’s trust fund or retirement plan. Approximately 65 percent of the subjects found in the 641 SARs were either: a) associated with some kind of business (named or un-named) or occupation13 ; b) identified by a job title, profession or other reference (Physician, Attorney, Restau- rant Owner, Retired, etc.); or c) identified by a business name or the nature of the business if the subject was listed as a company.

Image recognition and classification is one of the most actively pursued areas in the broad field of imaging sciences and engineering. The reason is evident: the ability to replace human visual capabilities with a machine is very important and there are diverse applications. The main idea is to inspect an image scene by processing data obtained from sensors.

Public health can be thought of as a series of complex systems. Many things that individual living in high income countries take for granted like the control of infectious disease, clean, potable water, low infant mortality rates require a high functioning systems comprised of numerous actors, locations and interactions to work. Many people only notice public health when that system fails. With widespread globalization occurring, public health issues have become transnational.

The purpose of this document is to describe the functionality and performance parameters for each GEOSAR instrument. The document is intended to be used to ensure the necessary compatibility for the 406 MHz beacon to satellite uplink and compatibility for the satellite to geostationary local user terminal (GEOLUT) downlink. The document is not intended for use as a specification for procurement of hardware for GEOSAR satellite repeaters.
