Indexing accuracy , Torque balancing cam , Roller alternation , Globoidal cam indexing mechanism

Globoidal cam indexing mechanism (GCIM) plays an important role in automation and machining tools. With the compact structure, a GCIM is able to reach the required precision on account of high stiffness and minimized backlash. The requirement to improve the indexing accuracy for GCIMs from industry applications drives the research going on. In this dissertation, two strategies to improve the indexing accuracy of GCIMs are proposed.The first strategy is by considering the manufacturing parameters...

Interference , Power Consumption , Ad Hoc Wireless Network

IEEE 802.11 MAC protocol uses two techniques to avoid interference ¡V physical carrier sensing and RTS/CTS handshake (virtual carrier sensing). Ideally, these two techniques can solve most of interference problem. But in normal situation a host cannot receive packet successfully unless the power of receiving signal is much higher than that of interference signal. This fact leads that other host can interfere the reception in farther distance than the distance between the transmitter and...

alkynylcopper complex , thioaminophosphine , tridentate ligand

Copper acetylides may be the intermediate of some carbon-carbon coupling reactions. Metal acetylides were studied extensively due to their variable coordination modes. In order to mimic the structure of the intermediate, we synthesized different thioaminophosphine copper(I) complexes and tested their reactivity toward alkynes in this thesis. We introduced steric effect by controlling the carbon-chain length between second and third donor atoms of ligands and electronic effect by altering substit...

Catalog Integration , Document Category Integration , Naïve Bayes Classifier , Hierarchical Category Integration , Hierarchical Clustering , Document Clustering

E-commerce applications generate and consume tremendous amount of online information that is typically available as textual documents. Observations of textual document management practices by organizations or individuals suggest the popularity of using categories (or category hierarchies) to organize, archive and access documents. On the other hand, an organization (or individual) also constantly acquires new documents from various Internet sources. Consequently, integration of relevant categori...

Channel Utilization , Ad Hoc Wireless Network , Dynamic Power Control , Adjust Power Control

In the present day, Ad Hoc wireless networks are quite convenient in a local area. But hidden terminal problems and exposed terminal problems exits in Ad Hoc networks. So how to avoid these problems and add channel bandwidth utilization efficiently in MAC (Medium Access Control) layer is a very critical topic. A number of MAC protocols have been presented to overcome these drawbacks, such as RTS / CTS ¡V based and busy tone ¡V based protocol.In this paper, we proposed a dynamic...

Highly Reliable Broadcast , TDMA-like , Ad Hoc Wireless Network , Directional Antennas

Ad hoc wireless networks are constructed by several mobile hosts and have a property that its topology is changed as mobile hosts moved. There is no stationary infrastructure or based station to coordinate packets transmissions and advertise the information of network topology or something important. The special networks are used in temporal wireless networks, such as battlefield, disease rescue place, and so on. So without any stationary infrastructure supported, mobile hosts can communicate wi...

strategy of global layout , multi-national business , competition advantage , human resources. , knowledge management

Finally, Taiwan was acceded into the World Trade Organization (WTO), opening up the gate for Taiwan to globalization. Therefore, businesses in Taiwan must brace for any challenges imposed by global competition caused by WTO. However, although globalization has created new opportunities in the international market, it will also give rise to increasingly intense competition for domestic market opportunities. Businesses must ponder and redefine how to stand up to an increasing number of competitors...

brain stem death , LPS , SSH

AbstractRecent studies demonstrated that LPS treated Sprague-Dawley rats induced a reduction (Phase I), followed by an augmentation (Phase II) and a secondary decrease (Phase III) in the power density of vasomotor components (0-0.8 Hz) in systemic arterial pressure signals. The molecular mechanisms underlie the progression toward death in the brain stem is unclear. In order to find out the differentially expressed genes between LPS-treated RVLM and saline-treated RVLM, we used suppression subtra...

cervical carcinoma , Skp2 , p27 Kip1 , MAP kinase

The F-box protein Skp2 (S-phase kinase associated protein 2) positively regulates the G1-S transition by controlling the cell cycle inhibitor p27Kip1. The p42/p44 mitogen-activated protein (MAP) kinase activation is also necessary for the cell cycle progression. p27Kip1 acts as a negative regulator of the cell cycle by inhibiting the activity of cyclin/cdk complexes during G0 and G1. RT-PCR, Western blotting and immunohistochemical staining were used to assay their relationship with cervical les...

GBM , astrocytomas , brain tumor , p-Akt , p27

Gliomas are the most common human brain tumors and are divided into four stages by WHO classification scheme. Benign gliomas are defined as grades I (Pilocytic astrocytomas) and II (Astrocytomas), whereas grade III (Anaplastic Astrocytomas, AA) and grade IV (Glioblastoma Multiforme, GBM) are malignant. Although both grades III and IV are malignant, the prognoses for these tumors are quite different. The 2-year survival rate for grade III gliomas is 50%, and grade IV is < 20 %. Mechanisms ...

fructose-1¡A 6-bisphosphate aldolase , purification , cloning , expression , Deinococcus radiodurans

The addition of Mn(II) to an early stationary-phase Deinococcus radiodurans RI culture could induce a new round of cell division (MnCD effect). The addition of Mn(II) could also stimulate the utilization of glucose and fructose in this bacterium. Class II fructose-1,6-bisphosphate aldolase (FBA) is an Mn-dependent key enzyme in pentose phosphate pathway. Therefore, in this research, we focused on the studies of the fba gene. Base on the gene sequence, FBA protein was composed of 306 amino acids,...

Field Functions , Implicit Surfaces , Blending Operations , Boolean Set Operations

Implicit surface modeling is attracting attention, because a complex object can be constructed easily and intuitively from some simple primitive objects, defined by primitive defining functions, using successive compositions of blending operations. Blending operations play a major role in implicit surfaces, because they can join intersecting primitive objects (operands) smoothly with transitions generated automatically by blending operators. Hence, this dissertation proposes three new methods: (...

Anisotropic Media , Polarization Transformation , LP to CP Polarizer

In this thesis, we investigate the transformation bandwidth and the thickness sensitivity of the anisotropic-slab linearly polarizes (LP) to circularly polarized (CP) polarizer. We define a transformation bandwidth and the thickness sensitivity based on the axial ratio. New methods are proposed that can eliminate the lengthy derivation and give deeper physical insight to the problem. Under the small reflection approximation, i.e., only the forward waves are considered, our methods can be applied...

Political behavior does exist in organizations. Perceptions of organizational politics affect decision-making of many issues in human resource departments from promotions to salaries. When members of organizations realize that political behavior will affect their promotions and salaries, thereby not fulfilling their expectations; the resulting perception may potentially bring an adverse effect on their work ethic. In recent years, many studies have taken place on the perceptions of organizationa...
