This research is an empirical study on the kind of special restaurants, aiming at understanding the growth strategy in food and beverage industry by means of system dynamics and building the management flight simulator for the research object. Based on several times of interviewing an Italian restaurant, the research model is built and composed of five major parts, which are ¡§Subsystem of customer and market,¡¨ ¡§Subsystem of employee,¡¨ ¡§Subsystem of capacity,¡¨ ¡§Subsystem of service quality and satisfaction¡¨ and ¡§Subsystem of finance.¡¨ Under the property of low repurchasing in this kind of restaurant, conclusions below are found after policy simulating: 1. Strategy of high-price with high-cost is suitable for this kind of restaurant¡¦s long-term management. Though the cost is higher, high-price strategy results in high customer satisfaction. With high revenue and steady customers, the possibility of insufficiency of growth and investment decreases. 2. Even if a restaurant has high customer satisfaction and sufficient capital, growing too fast will fail it easily. Growing too fast will fail a restaurant because of insolvency, especially the kind of special restaurant, of which the frequency of patronage is not as high as that of common restaurants. Therefore, quick expansion will bring out huge expenditure; thus, fails a restaurant even if there is high service quality and high satisfaction. 3. Advertisement makes future customers patronize earlier. Maintaining frequent customers is a better strategy. Advertisement makes future customers patronize earlier, but its effect does not last as long as word-of-mouth effect. 4. Business environment is better when all competitors compete with each other by means of high-price strategy. By adopting low-price strategy, a restaurant will draw lots of customers and need to expand itself. Quick expansion, however, reduces customer satisfaction and leads to fail eventually. Instead, managers who adopt high-price strategy run business better. As a result, business environment is better when market players adopt high-price strategy.

This article is about building a dynamic model of an Italian food restaurant in Kaohsiung, Taiwan. The model contains six sectors, including human resource sector, kitchen sector, quality sector, training sector, market sector and the financial sector. Depending on these six sectors we build a computer simulation model. With this computer simulation model can help people get better understanding of the real operational system and can have better insights of the restaurant management. In this article, we found out that the restaurant manager needs to emphasize the quality and training of their employees. If the restaurant grows without enough qualified employees, the growth will meet its limit and has problems like quality decline, working overtime, high turnover rate, customer base decline and may cause the restaurant to close up. In this article, we also found out that the training must both emphasize the professional training and ethic training and it is better to emphasize a little more on the ethic training. If the restaurant managers focus only on the professional training, it will bring serious problems. Since it has many conflicts during the work, the ethic training can help employees having more stable, social emotions for better customer service and build a trust and harmonious working atmosphere. Otherwise, the conflicts between the coworkers may cause service delay, service mistakes, increasing cost and high turnover rate. All these problems will affect the operation of the restaurant management in long term. In this article, the dynamic model contains many soft variables of the restaurant management. It can provide the learner of dynamic model building to learn about the soft variables modeling.

This research tries to observe an advertizing printing company¡¦s business model and understand the interaction between different policies implemented on the company by System Dynamics. Futhermore, building Management Flight Simulatior can let one simulate the situation and policies to find the effective policies. After the simulation and the evaluation, we find that if the company only pays attention to marketing but didn¡¦t make efforts on the employees¡¦ training, it will block the company¡¦s growth, and the manager always ignored this problem. However, if we only make efforts on training the employees or hiring new employees, it will be just a waste of money in the long run. Therefore, the manager should enlarge his thinking boundary, and considerate not only marketing but training, and even many other policies, and the most important is their interaction, at appropriate time.

<p>In mobile digital devices, low power consumption is an important matter to reduce the need for a heavy and big battery. One way of reducing the power consumption is to construct the hardware so that the performance is optimal for the application. The demand of performance is dependent of the tasks that the device will be performing. This is where scalable structure of the hardware is an idea to solve the problem. </p><p>This master thesis serve as a starting point for developing a digital signal processor with scalable structure. The digital signal processor is a common and important part of digital processing. Scalable struture is in this case adding and removing parts of the memory and/or the instruction set, and to make the data wordlength variable. The development is simplified by modeling it on an existing processor. The result of this master thesis is an instruction simulator written in C language. The simulator will be a model for development of the hardware.</p>

<p>Syftet med studien är att undersöka lastbil- och bussimulatorers för- och nackdelar i användandet som pedagogiskt verktyg. I undersökningen har intervjuer med tre pedagoger och tre studenter genomförts för att utvärdera simulatorer som pedagogiskt verktyg. En strävan att informera och väcka ett intresse av tekniken som hjälpmedel i undervisningen har också legat till grund för arbetet. Enligt flera forskare finns ekonomiska och tidseffektiva vinster med att använda simulatorer i undervisningen. Fördelar med den virtuella miljön är att studenterna kan lära sig hur det är att köra ett stort fordon, möjlighet finns likaså att öva på oförutsedda kritiska händelser. Studenterna och pedagogerna som intervjuades ser fördelar med tidsvinsten samt att det är ett bra verktyg för nybörjaren. Nackdelar med fordonssimulatorn finns i återgivningen att efterlikna ett riktigt fordon samt den grafiska miljön. Studenter och pedagoger är väl överens om återgivning av miljön i simulatorn är mycket bra men den innehåller också brister. Informanterna har alla reflekterat över detta men ingen har antytt att det påverkat deras inlärning negativt. Fordonssimulatorer är relativt nytt i Sverige, idag finns det ett fåtal fordonssimulatorer i våra skolor. Tekniken har tidigare funnits men återgivningen av miljön och kostnaden har varit ett starkt argument för att inte investera i verktyget. Tekniken och kostnaden har förändrats och gör simulatorn till både ett ekonomiskt och pedagogiskt hjälpmedel</p>

Current practices in energized treatments, using gases and foams, remain rudimentary in comparison to other fracturing fluid technologies. None of the available 3D fracturing models for incompressible water-based fluids have been able to capture the thermal and compositional effects that are important when using energized fluids, as their constitutive equations assume single-phase, single-component, incompressible fluid flow. These models introduce a bias in fluid selection because they do not accurately capture the unique behavior of energized fluids. The lack of modeling tools specifically suited for these fluids has hindered their design and field implementation. This work uses a fully compositional 3D fracturing model to answer some of the questions surrounding the design of energized treatments. The new model is capable of handling any multi-component mixture of fluids and chemicals. Changes in fluid density, composition, and temperature are predicted using an energy balance equation and an equation of state. A wellbore model, which relates the surface and bottomhole conditions, determines the pumping requirements. Fracture performance is assessed by a fractured well productivity model that accounts for damage in the invaded zone and finite fracture conductivity. The combination of the fracture, productivity, and wellbore models forms a standalone simulator that is suitable for designing and optimizing energized treatments. The simulator offers a wide range of capabilities, making it suitable for many different applications ranging from hydraulic fracturing to long-term injections for enhanced oil recovery, well clean-up, or carbon sequestration purposes. The model is applicable to any well configuration: vertical, deviated, or horizontal. The resolution of the full 3D elasticity problem enables us to propagate the fracture across multiple layers, where height growth is controlled by the vertical distribution of the minimum horizontal stress. We conducted several sensitivity studies to compare the fracture propagation, productivity, and pumping requirements of various fluid candidates in different reservoirs. The results show that good proppant placement and high fracture conductivities can be achieved with foams and gelled fluid formulations. Foams provide a wide range of viscosities without using excessive amounts of gelling agents. They also provide superior fluid-loss control, as the filter-cake is supplemented by the presence of gas bubbles that reduce liquid-flow into the porous medium. CO₂, LPG, and N₂ expand significantly (by 15% or more) as the reservoir heats the fluid inside the fracture. These fluids show virtually no damage in the invaded zone, which is a significant improvement upon water-based fluids in reservoirs that are prone to water blocking. These results, however, are contingent on an accurate fluid characterization supported by experimental data; therefore, our work advocates for complementary experimental studies on fluid rheology, proppant transport, and fluid leak-off. A comprehensive sensitivity study over a wide range of reservoir conditions identified five key reservoir parameters for fluid selection: relative permeability curve, initial gas saturation, reservoir pressure, changes to rock mechanical properties, and water-sensitivity. Because energized fluids provide similar rheology and leak-off behaviors as water-based fluids, the primary design question it to evaluate the extent of the damaged zone against costs, fluid availability, and/or safety hazards. If the fluid-induced damage is acceptable, water-based fluids constitute a simple and attractive solution; otherwise, energized fluids are recommended. Notably, energized fluids are well-suited for reservoirs that are depleted, under-saturated, and/or water-sensitive. These fluids are also favorable in areas with a limited water supply. As water resources become constrained in many areas, reducing the water footprint and the environmental impact is of paramount concern, thereby making the use of energized treatments particularly attractive to replace or subsidize water in the fracturing process. / text

When developing a wireless communications system, it is useful to perform simulations of the radio context in which the system has to operate. A radio link is substantially composed by three parts: transmitting segment, transmission channel and receiving segment. We focus our attention on the radio channel propagation. We proposed two geometrical models of a territory corresponding to a determined flight area and, after importing the data needed to estimate our parameters, we compared our results with the channel soundings in literature, obtaining comparable values.
