  • Physical design involves evaluating solution technologies. In this module, you will learn about some of the solution technology types and some evaluation criteria to consider for each of them. Later, you will use this information to investigate specific MicrosoftÆ solution technologies. Microsoft Official Curriculum (MOC), available to IT Academies at a discounted price, is professional courseware intended for IT professionals and developers who build, support, and implement solutions by using Microsoft products and technologies.

  • This paper proposes a novel method for learning probability models of subcategorization preference of verbs. We consider the issues of case dependencies and noun class generalization in a uniform way by employing the maximum entropy modeling method. We also propose a new model selection algorithm which starts from the most general model and gradually examines more specific models.

  • This paper discusses a decision-tree approach to the problem of assigning probabilities to words following a given text. In contrast with previous decision-tree language model attempts, an algorithm for selecting nearly optimal questions is considered. The model is to be tested on a standard task, The Wall Street Journal, allowing a fair comparison with the well-known trigram model.

  • Network connections should therefore be protected, at a level based on the risk. The assumption must be that the connecting parties are to a certain degree hostile and have to be strictly constrained to the access for which the connection was agreed. The connecting parties will, after all, have their own security policies and risk management philosophies, and these may vary considerably. Each security management domain will need to apply stringent logical access controls, and should strongly consider using firewalls and related technologies to defend their 'perimeter'....

  • Moreover, typically, previous work investigated en- forcing a given resource partitioning of a single re- source, within a single software tier at a time. In our own previous work in the area of dynamic parti- tioning, we have investigated either partitioning mem- ory, through a simulation-based exhaustive search ap- proach [24], or partitioning storage bandwidth, through an adaptive feedback-loop approach [23], but not both.

  • We consider the problem of correcting errors made by English as a Second Language (ESL) writers and address two issues that are essential to making progress in ESL error correction - algorithm selection and model adaptation to the first language of the ESL learner. A variety of learning algorithms have been applied to correct ESL mistakes, but often comparisons were made between incomparable data sets. We conduct an extensive, fair comparison of four popular learning methods for the task, reversing conclusions from earlier evaluations. ...

  • We consider a very simple, yet effective, approach to cross language adaptation of dependency parsers. We first remove lexical items from the treebanks and map part-of-speech tags into a common tagset. We then train a language model on tag sequences in otherwise unlabeled target data and rank labeled source data by perplexity per word of tag sequences from less similar to most similar to the target. We then train our target language parser on the most similar data points in the source labeled data. ...

  • In hierarchical phrase-based SMT systems, statistical models are integrated to guide the hierarchical rule selection for better translation performance. Previous work mainly focused on the selection of either the source side of a hierarchical rule or the target side of a hierarchical rule rather than considering both of them simultaneously. This paper presents a joint model to predict the selection of hierarchical rules.

  • The algorithm is implemented on top of the Selective Gain Computation (SGC) algorithm (Zhou et al., 2003), which offers fast training and high quality models. Theoretically, the new algorithm is able to explore an unlimited amount of features. Because of the improved capability of the CME algorithm, we are able to consider many new features and feature combinations during model construction.

  • As can be seen in Table 1, the pre-service teachers had diverse linguistic and cultural backgrounds. 2 Selection of the pre-service teachers, while not designed to be representative, provided a broad student teacher perspective on issues related to teaching ESL writing. The participants represented a diverse set of backgrounds and experiences. Seven were native English speakers. Five were second language speakers of English, with Korean, French and Portuguese as their first language backgrounds.

  • Microwaves are generally considered to be a specific part of the wide radio frequency spectrum. The band from 300 MHz to 30 GHz is typically considered to be “microwaves,” for example by the Institute of Electrical end Electronics Engineers (IEEE), although many of us prefer to set the lower limit somewhat higher—perhaps at 1 or even 3 GHz. Above 30 GHz, the term “millimeter waves” is used. High school physics suggests that we are talking about wavelengths ranging from about 30 cm down to 10 mm...

  • This chapter on disk brakes and clutches will consider annular contact disk clutches and both caliper and annular contact disk brakes, as illustrated in Figures 1, 2, and 3. Caliper disk brakes, as shown in Figure 1, are used on aircraft, automotive, industrial, and mining equipment. Their two main advantages compared to drum brakes are greater heat dissipation, and hence less fading, because of their open construction, and a more uniform braking action, due to self-cleaning by brake pad abrasion.

  • Disaster recovery back-up tapes or other media should be kept solely as a security precaution and are not intended to serve as a records retention tool. In the case of disaster, the back-up would be used to restore lost records. Agency records that have not met their retention should not be disposed of on the basis of the existence of a back-up. If, for any reason (for instance, a disaster erases e-mails on an agency server), the only existing copy of an item that has not met its retention period is on a back-up tape or other medium, the agency must...

  • Previous Page 4.1 Selection of an Appropriate Mold When considering the use of stack molds, especially for fast cycling products, special measures must be planned to remove the huge amounts of products. Depending on the shape of the product, these measures could be any of a number of controlled ejection methods, conveyors, stackers, packing machines etc. Figure 4.70 shows a typical cup stacker. The stacker is positioned at the rear of the molding machine. It consists of an unscrambling vibratory conveyor (A) that receives the randomly ejected, scrambled containers from under the mold.

The methodology for assessing the operating efficiency of an entity will be quite different from that for attempting to measure the effectiveness of a programme in achieving its stated objectives. These two kinds of audits involve collecting and analysing different kinds of data from different sources.

The desire and intent to have children among HIV-infected individuals may increase because of improved quality of life and survival following commencement of anti-retroviral treatment. In developing countries such as South Africa, where the largest number of people living with HIV/AIDS worldwide reside, specific government reproductive health policy and service provision for HIV-infected individuals is underdeveloped.

  • Displacing older people as heads of households and depriving them of their autonomy in the name of affection are cultural norms even in countries where the family is the central institution and the sense of filial obligation is strong (11). Such infantilization and overprotection can leave the older person isolated, depressed and demoralized, and can be considered a form of abuse. In some traditional societies, older widows are abandoned and their property seized.
