  • This study investigated the effects of Na 2 SO4 additive in the positive electrode on the performance of sealed lead-acid cells. The additive Na 2 SO4 in the cured plates can reduce the 4BS crystal size, which produces a smaller a-PbO 2 and b-PbO 2 crystal size in the formed plates, which will have a larger surface area. The plate’s chemical composition is independent of the amount of Na 2 SO4 additive in the positive electrodes. Plate composition relies only on the cure temperature conditions. ...

  • Text prediction is the task of suggesting text while the user is typing. Its main aim is to reduce the number of keystrokes that are needed to type a text. In this paper, we address the influence of text type and domain differences on text prediction quality. By training and testing our text prediction algorithm on four different text types (Wikipedia, Twitter, transcriptions of conversational speech and FAQ) with equal corpus sizes, we found that there is a clear effect of text type on text prediction quality: training and testing on the same text type gave percentages of saved...

  • Accurate estimates of the software cost are a critical part of effective program management, particularly for large, complex systems. Predicting the cost of software has evolved, but the practice of cost prediction is far from perfect. Military and commercial programs alike are replete with examples of software cost estimates that differ

  • This paper explores the relationship between the translation quality and the retrieval effectiveness in Machine Translation (MT) based Cross-Language Information Retrieval (CLIR). To obtain MT systems of different translation quality, we degrade a rule-based MT system by decreasing the size of the rule base and the size of the dictionary. We use the degraded MT systems to translate queries and submit the translated queries of varying quality to the IR system. Retrieval effectiveness is found to correlate highly with the translation quality of the queries.

  • Liabilities and the impacts on financial performance of the Vietnamese listed small and medium-sized enterprises. This research aims to examine the relationship between liabilities and firm performance of the Vietnamese listed small and medium-sized enterprises (SMEs). We explore a panel data set of 61 listed SMEs in Vietnam from 2011 to 2014 and apply random-effects models.

  • Emphasis on effect sizes is a rapidly rising tide as over 20 journals in various fields of research now require that authors of research reports provide estimates of effect size. For certain kinds of applied research it is no longer considered acceptable only to report that results were statistically significant. Statistically significant results indicate that a researcher has discovered evidence of a real difference between parameters or a real association between variables, but it is one of unknown size.

  • In the present article, we report the biosensor can detect superparamagnetic nanoparticles (less than 10 nm in size) at various and low particle concentrations, which is of the importance role in biosensing applications. The nanoparticle ferrite (Fe3O4), Cobalt ferrite (CoFe2O4), Nickel ferrite (NiFe2O4) nanoparticles were synthesized by the high temperature thermal decomposition precursor method.

  • This article presents an approach to credit quality research including both internal and external assessment; sets up research model on 4 elements of credit service quality and overall credit quality efficiency, on that basis sets up measurement scales of 30 observation variables of 4 quality components - independent variable and 5 observation variables of overall credit quality capacity - dependent variables. The use of this research scale and model helps to evaluate the situation of quality components and the effects of each independent variable on the dependent variables in the model.

  • In this paper, we adapt a mechanism named atomic ring maintenance for Chord to mitigate the effect of churn. Simulation results show significant improvement in successful ratio of lookups for modified Chord protocol in high churn condition while latency of successful lookups is as good as that in basic Chord. Simultaneously, we also evaluate correlation between successful lookup ratio and network size and churn rate.

  • Multilayer ceramic capacitors (MLCC) are indispensable electronic components for advanced electronic technology2-12, but larger capacity and smaller size are needed for future electronic devices. To meet these needs, BaTiO3 particles were downsized, but ferroelectric ceramics lose their ferroelectricity when their particle size is decreased and lose ferroelectricity entirely at a critical size2-11. This is known as the size effect and it impedes the progress of MLCC, so a novel solution has been eagerly anticipated....

  • Although mobile devices, cellular phones, Personal Digital Assistants (PDAs) and other handheld devices have hardware constraints such as small screen, small storage, low CPU speed, and low resolution, their popularity has been enormously increasing. This is enhancing the opportunities for researchers to overcome those open problems caused of small size hardware constraints. However, still the biggest difficulty is that these devices are too difficult to load today’s visual information because most current information is based on a large visual documentation.

  • Staring at a shelf full of Photoshop books at the local bookstore, it seems that there are more special-effect “cookbooks” and technical tomes than anyone would ever care to read. The problem is that none of those “cookbooks” provide enough detail to really let you feel like you understand the program (blindly following the listed steps just doesn’t do it), and all of the technical books are deep into terms like rasters, vectors, and bit-depth settings. That’s the primary reason that most people aren’t truly comfortable with Photoshop.

  • The bo is an excellent weapon but one of the more impractical ones because of its size. It is a piece of hard wood about six feet in length, and therefore cannot be easily concealed or carried in a car or on your person. Still, it has remained a favorite karate weapon for years because of its versatility and beauty when used in the hands of a master.

  • An introduction into Online Advertising. – How it all began. If you ever wondered when it all started, the answer is October 1994 on HotWired, the predecessor to today’s Wired News. The ads were for Zima, Club Med, and AT&T and measured 468 pixels by 60 pixels. This seemingly awkward size effectively filled the horizontal length of a maximized web browser using a monitor resolution of 640x480 pixels (the standard at the time). This banner size became the de facto standard is still widely used today.
