The analysis of growth strategy in Fine chemicals trading company

Lo, Chao-Lung 28 July 2010 (has links)
The effective way to a Taiwanese company for survival is base on ¡§growth strategy analysis¡C Base on analyze the outside environment and inside human recourses and capability of execution of a company ¡CWe think¡A for each company ¡A how to analyze and execute are very important subjects to them¡C The researches were concentrated in strategy and efficacy on running a company¡C Good strategy result in good profits in company¡C Different environment in different stage for different company in same strategy will not outcome the same results (profits)¡CThe basic resources are quality of manpower¡Ainside resources¡A outside resources¡A ability for execution¡A core competences¡A flexible process of integration¡C Beside the ability of execution and core competence¡A a preferable strategy is also key factor in growth¡A Right strategy and effective execution can achieve a target of growth to maintain a successful sustain growth in fine chemical industries for a trading company. As the demand of customers from this globalization and the life cycle is getting shorter. The profits and advantages are harder to sustain¡C We could emphasis core business competence and reducing the risk in our business by cooperate with suppliers and down stream users to maximum profit by long term relationship. For pursuing profit, we need to reducing cost and has our own competitive resources and capability. In order to create profits and growth, we need to maintain our sustainable advantages. IT capability is a good ability manage the vertical integration of supply chain and coalition in business.

A pkp study of the earth's core using the warramunga seismic array

Bertrand, Aimee Elizabeth Surrendra January 1972 (has links)
PKP core phases recorded at the U.K.A.E.A. - type seismic array, WRA, in Northern Territory, Australia over the distance range 113° to 176° are used to determine a velocity-depth model for the earth's core. Paper recordings played out at high speed (40 mm/sec) from analog magnetic tape with amplitude gain control and narrow bandpass filters provided the data available for analysis. Such data enabled precision measurement of relative times between seismic traces. Four distinct travel time branches were observed. Two of these are the well-known PKP[formula omitted] and PKP[formula omitted] branches which are trans- mitted through the outer and inner cores, respectively. The two additional branches are forerunners to the DF branch at distances less than 143°. In recent years, the existence of one of these branches designated PKP[formula omitted], has been accepted to account for ob-served precursors. However, the existence of a distinct second branch, designated PKP[formula omitted], has been a subject for debate. Since the precursor branches provide information about the "transition region" between the fluid outer core and the solid inner core, the identification in this study of two distinct sets of forerunners is of some importance. Traveltime and traveltime gradient (dT/d∆ ) measurements of each phase observed on the seismograms were made. The dT/d∆ values were measured by a least-squares technique. These measurements were strongly perturbed by structure beneath the array and it was necessary to correct for the effect by an empirical approach. The corrected dT/d∆ values were smoothed by the method of summary values and, for comparison, by a polynomial regression technique. The smoothed dT/d∆ values for all four branches were inverted by the Herglotz-Weichert method in order to obtain a velocity-depth model for the earth's core. The final velocity model, UBC1, determined in this manner was the one which gave the best fit to all observations in this study. Near a depth of 4000 km., UBC1 required a -slight reduction in the Jeffreys-Bullen (1940) velocities in order to obtain travel times that agreed with the observations for the outer core. The model exhibits three velocity discontinuities at depths 4393 km, 4810 km, and 5120 km. The magnitude of the velocity increases at the discontinuities are 0.10, 0.24 and 0.92 km/sec, respectively. These discontinuities define two shells surrounding the inner core. In the outermost shell, 417 km thick, the velocity gradient is near zero in magnitude. In the second shell, 300 km thick, the velocity gradient is slightly negative. / Science, Faculty of / Earth, Ocean and Atmospheric Sciences, Department of / Graduate

Partition Timing Routing Protocol in Wireless Ad Hoc Networks

Lin, Tsung-Hsien 07 July 2003 (has links)
Ad Hoc Networks are transmission networks on the structure of wireless networks by consisting of many mobile hosts. But it is no need to use any support by other communication infrastructures like Base Stations, and directly use wireless networks for data-transmission. Because the feature of per host as fast movement, every host can join or go away as it likes, thus, the topology appeared from Ad Hoc networks will have higher probability to make packet loss or transmission delay and cause network flooded to do unnecessary re-send and lose the flow of running data. We will explain generally some relative protocols of setting up routes and possible problems. Besides, describe relative researches of how to solve and reduce the possibility of problem happened. Then, we will bring up a new constructive protocol (Partition-Timing Routing Protocol¡APTR), the protocol can adjust neighboring nodes of covered scope to select certain node to be own core node, if any covered node needs to transmit data to others outside the scope, it has to be managed by core node. Besides, the timing for update and adjust data of per covered scope is different too and not as same as other ways which update timing is at the same time to reduce the load of the entirely network and more changeable. Furthermore, it may increase the rate of update of per scope to get the target of succeeding data-transmission. The simulation results will appear that the load and possibility of data transmission has more advantages than other ways.

A study of how do Taiwanese electronics company develop the products relay to Automotive

Chen, Kuan-Yao 31 July 2007 (has links)
The trend of vehicle industry has been changed due to well development of electronic and information technology , the electronic industry has become an important part of vehicle innovation and research. Taiwan has pivotal status of electric industry in the world, while the opportunity of car electronic was bloomimg, what stratage should Taiwan's electronics company take to hold out the important role ? The mainly research discusses was below: 1. Taiwan has superiority ability of design and production on the semiconductor and the electronic industry, and has the high design flexibility as well as the formidable conformity ability, how the Taiwan electronics industry call into play the core ability and connects with the mainstream of global vehicle industrial, strides in the vehicle to use the electronic industry? 2. By increase of installs the electronic component on vehicle year by year, the vehicle industry push the electronic market growth fast, simultaneously, it provides an oportunity for Taiwan electronic industry; How does the Taiwan electronic industry grasp the opportunity, adopts corresponding ways to enters the global car electronic market? In view of the above questions, this research was doing by collectiing secondary data and the market analysis information, auxiliary to interview several company whom develops automotive electronic products, induces what countermeasures Taiwan electronics company takes by extend their advantage to enter the car electrics industry. The result of this research is found is no matter how ability that company obtain or take what kind of stratage, but the key factor to success was doing daily work practically.
