Abstract:

Over the last decade, the diesel engine has made dramatic progress in its performance and market penetration. However, in order to meet future emissions legislations, Nitrogen Oxide (NOx) and particulate matter (PM) emissions will need to be reduced simultaneously. Nowadays researchers are focused on different combustion modes like homogeneous charge compression ignition (HCCI) combustion and premixed charge compression ignition (PCCI) which have a great potential for both low soot and low NOx. In order to achieve these combustion modes, different injection strategies have been investigated. T

Utsläppsrätter och energisäkerhetsfrågan har infört förnybart bränsle på marknaden. EU: s mål att använda 20% förnybar energi i transportsektorn till 2020 har tvingat fordonstillverkarna att göra fordonen mer kompatibla med biobränsle. Biodiesel FAME (fettsyrametylestrar) har införts på den europeiska marknaden som alternativ till diesel och som för närvarande blandas med diesel. Förutom kvaliteter så som högt cetantal, energitäthet och låg svavelhalt är biodiesel mycket benäget att oxidera och korrodera samt att det är mycket hygroskopiskt, vilket orsakar problem, särskilt i insprutningssyste

Abstract:

As embedded systems continue to evolve and the number of applications they support continues to increase, so does the diversity of the hardware they employ. As a result, the Field Programmable Gate Arrays (FPGAs), which have become fundamental elements in their design, have advanced in size and complexity as well. Because of this, it is now impossible to ignore the security implications that accompany such a progression. It is then not only important to prevent malicious attacks targeted at FPGAs from extracting the intellectual property contained in their configuration, but to now extend the

Abstract:

A global steady increase of energy consumption coupled with the decline of conventional oil resources points to a more aggressive exploitation of heavy oil. Heavy oil is a major source of energy in this century with a worldwide base reserve exceeding 2.5 trillion barrels. Management decisions and production strategies from thermal oil recovery processes are frequently based on reservoir simulation. A proper description of the physical properties, particularly oil viscosity, is essential in performing reliable modeling studies of fluid flow in the reservoir. We simulated cyclic steam injections

A novel method to enhance oil production during cyclic steam injection has been developed. In the Top-Injection and Bottom-Production (TINBOP) method, the well contains two strings separated by two packers (a dual and a single packer): the short string (SS) is completed in the top quarter of the reservoir, while the long string (LS) is completed in the bottom quarter of the reservoir. The method requires an initial warm-up stage where steam is injected into both strings for 21 days; then the LS is opened to production while the SS continues to inject steam for 14 days. After the initial warm-u

Testing Web Services applications and their Fault Tolerance Mechanisms (FTMs) is crucial for the development of today's applications. The performance and FTMs of composed service systems are hard to measure at design time because service instability is often caused by the nature of the network. Testing in a real internet environment is difficult to set up and control. However, the adequacy of FTMs and the performance of Web Service applications can be tested efficiently by injecting faults and observing how the target system performs under faulty conditions.

Abstract:

Current practice in U.S. underground coal mine high-voltage distribution systems is to attempt to limit ground fault current to 25 Amperes and de-energize the circuit at 10 Amperes. However, the significant amount of system capacitance due to the use of shielded cables can cause ground fault current to be two or three times the intended ground fault limit. Consequently, this practice can cause several issues such as ground fault currents significantly exceeding the neutral grounding resistor current limit, loss of relay selectivity in the distribution system, and transient overvoltages in cert

With the advance of IC processing technology, the internal operating voltage must be lower to reduce the leakage current and power consumption. This turn of event can lead to a smaller noise margin and a poorer electromagnetic immunity of the ICs. Among the immunity testing standards on ICs, the Direct Power Injection (DPI) method is oft taken to be the method of choice by the mainstream industries worldwide. The DPI test process has been defined by international standard under the protocol

碩士<br>國立雲林科技大學<br>工業工程與管理系<br>102<br>The injection molding process is an import process for plastic manufacturing. The resin science is progressing rapidly so that more and more types of plastics can be used by this process. Injection molding can also provide a short manufacturing time. The complexities of the structural parts are easily made via Injection molding. Among all of the plastic manufacture defects, the warpage usually perplexes many engineers. The warpage is caused by the melting resin cooling inconstantly and internal stress being released. Injection Compression Molding (ICM) is o

Today, reducing carbon emission and energy is the goal for world development. Permanent magnet synchronous motor（PMSM）compare with other type motors has the merits for low noise, high power density, high efficiency, and less maintenance, which has been widely used in industry and household appliances. Furthermore, the high power semiconductor devices is continued development, the exploitation of micro processing technology which has abil

In this study, we have altered the precursor concentration and reaction time to analyze the growth mechanism of SnS2. The results show that stable SnS2 nanosheets can be obtained when the precursor ratio of tin and sulfur was 1:5 with a one hour reaction time period and the maximum particle size obtained is about

Unfortunately, HTML5-based apps are also susceptible to cross-site scripting attacks like most web applications. Attackers can inject malicious scripts from many different injection channels such as QR Code and Wi-Fi access points. In this paper, we propose a new way to detect a known malicious script injected by using
