Development Of A Computer Simulation Game Using A Reverse Engineering Approach

Business simulation games are widely used in the classroom to provide students with experiential learning opportunities on business situations in a dynamic fashion. When properly designed and implemented, the computer simulation game can be a useful educational tool by integrating separate theoretical concepts and demonstrating the nature of actual business decisions. This article presents the author’s reverse engineering approach in developing a simulation game for an operations management course. With the ultimate goal of enhancing student learning, the project’s objective was to develop a focused game with easy to use tools and controls that could be played in the last three weeks of a semester. Based on an old simulation game, PROSIM III, the new system eliminated rarely used modules and complex rules, and focused on the planning and scheduling aspects of the original game. New analysis tools and attractive screens were added and the simulation process was simplified by employing Internet technologies. Survey responses showed that the new system, PROSYS, was well received by the students. The methodology, findings and experiences presented in this article should be beneficial for other instructors considering similar projects

Comparative Study of Alternative Computing Technologies for Speed and Density

As we design faster and denser silicon hardware to increase computing performance, some limitations started to appear. It is apparent that these limitations will stifle the growth of performance in the near future. In order to overcome these limitations, alternative computing technologies started to emerge. Among many attempts, biological computing, DNA computing, quantum computing and optical computing emerged as promising technologies. In this present paper we give state of the art of alternative computing technologies and compare them from the viewpoint of speed and density and classify the type of problems they can be used for solving. The driving force behind the search for alternative technologies and the major trends are also explained

Peer Response in L1 Writing: Impact on Revisions and Student Perceptions

Peer response is a strategy frequently used for improving the quality of students’ writing both in L1 and L2 writing context (Paulus, 1999; Baker, 2016). Studies has investigated how peer response impacts students’ writing influence of peer response on revisions in student writing in ESL context (e.g. Paulus, 1999; Min, 2006; Ting & Qian, 2010; Baker, 2016). However, most of the literature focuses on how peer-response influences student revisions in second-language learning context (Baker, 2016). This study addressed the gap in the literature by analyzing student revisions after peer-response in a writing classroom adopting multiple-draft approach in L1 writing context. The study also explored how L1 writers perceive peer response in writing classrooms. Using Faigley & Witte’s (1981) taxonomy of revisions, 31 undergraduate students’ essay drafts were analyzed quantitatively to explore how L1 writers revise their essays after each peer response session. Students were assigned a reflection essay after the writing assignment that consisted of prompts addressing their peer response experience. These reflection essays were qualitatively analyzed and coded based on themes in order to explore students’ perception of peer-response. The results showed that L1 writers mostly make predominantly surface-level revisions in their writing. This finding is consistent with studies conducted in ESL/EFL context (Paulus, 1999; Min, 2006; Ting & Qian, 2010), but vastly different from what has been found in L1 context (Faigley & Witte, 1981; Baker, 2016). This result may be explained by the difference in students’ writing proficiency and how it impacts revisions. It was also found that L1 writers show positive perceptions of peer-response in writing classrooms overall

Fracture abundance and strain in folded cardium formation, Alberta fold-and-thrust belt, Canada

textThe folded and thrusted Mesozoic clastic sequence of the Canadian Rocky Mountain foothills forms important hydrocarbon reservoirs. Understanding the distribution of natural fractures, their evolution, and timing of formation relative to the evolution of the fold-and-thrust system could potentially improve exploration and development outcomes in these otherwise tight unconventional reservoirs. However, the formation of fractures and their timing relative to folding and thrusting have remained unclear. I investigated the relation between folding and fracture formation in the Upper Cretaceous Cardium Sandstone by combining field structural observations and kinematic modeling of the fold-and-thrust belt evolution. I explored the relationship between fracture intensity and fracture strain with structural position by analyzing fracture spacing or frequency and aperture data collected along outcrop and micro-scanlines in the backlimb, in the forelimb close to the crest, and in the steeper dipping forelimb away from the crest of the Red Deer River anticline. Fracture frequency and aperture data collected both at the outcrop and micro scales indicate that variation in fracture strain is small across these three structural domains of the fold, with somewhat lower fracture intensity in the forelimb close to the crest. These fracture strain measurements are qualitatively consistent with calculated horizontal strain in the tectonic transport direction obtained through kinematic numerical models that simulate fold development associated with slip along the underlying Burnt Timber thrust. The models predict roughly similar amount of horizontal extension in both the back and forelimbs, and somewhat lower extension in the upper forelimb during early development of the Red Deer River anticline. Fracture formation early during fold development is consistent with the field structural observations of shear reactivation during later stages of folding. This combined kinematic modeling and field structural study demonstrates that deforming fold and thrust belts can undergo a complex evolution of bed-parallel extension in both space and time, resulting in spatially variable fracture formation in such structurally complex subsurface reservoirs.Geological Science

The effect of vascular graft and human umbilical cord blood-derived CD34+ stem cell on peripheral nerve healing

AIM: There are many trials concerning peripheral nerve damage causes and treatment options. Unfortunately, nerve damage is still a major problem regarding health, social and economic issues. On this study, we used vascular graft and human cord blood derived stem cells to find an alternative treatment solution to this problem. MATERIAL AND METHODS: We used 21 female Wistar rats on our study. They were anesthetized with ketamine and we studied right hind limbs. On Group 1, we did a full layer cut on the right sciatic nerve. On Group 2, we did a full layer cut on the right sciatic nerve, and we covered synthetic vascular graft on cut area. On Group 3, we did a full layer cut on right sciatic nerve, and we covered the area with stem cell applied vascular graft. RESULTS: At the end of postoperative 8. weeks, we performed EMG on the rats. When we compared healthy and degenerated areas as a result of EMG, we found significant amplitude differences between the groups on healthy areas whereas there was no significant difference on degenerated areas between the groups. Then we re-opened the operated area again to reveal the sciatic nerve cut area, and we performed electron microscope evaluation. On the stem cell group, we observed that both the axon and the myelin sheet prevented degeneration. CONCLUSION: This study is a first on using synthetic vascular graft and cord blood derived CD34+ cells in peripheral nerve degeneration. On the tissues that were examined with electron microscope, we observed that CD34+ cells prevented both axonal and myelin sheath degeneration. Nerve tissue showed similar results to the control group, and the damage was minimal. © 2018 Ali Yilmaz, Abdullah Topcu, Cagdas Erdogan, Levent Sinan Bir, Barbaros Sahin, Gulcin Abban, Erdal Coskun, Ayca Ozkul

Seismic Assessment of Tall Buildings Designed According to the Turkish Building Earthquake Code

For the first time, the 2018 edition of the Turkish Building Earthquake Code has added a dedicated chapter for the design of high-rise buildings in earthquake-prone areas. Keeping in view the widely practised design option of rigid shear walls at the centre of a high-rise structure, the latest code has additionally defined limits for shear-wall axial forces in high-rise buildings. The new shear-wall axial force limits have not been independently investigated for optimal design and criticality. This calls for a detailed investigation of the newly defined axial force limits for the design of high-rise buildings in Turkey, where seismic activity has historically remained high. This study, therefore, investigates the effect of variation in limit values of shear wall axial forces on the collapse prevention of such buildings. A high-rise building designed entirely according to the code was chosen as the base model. The location of the building is in Istanbul, which has the highest number of tall buildings as compared to other cities in Turkey. A total of 7 alternative models were created by changing the concrete material class and the thickness of shear walls. This approach allowed us to quantify the effect of shear-wall thickness and its criticality against another important design consideration, i.e., the compressive strength of concrete. Forty different earthquake ground motion records were used to analyse the models to determine how critical the axial force ratio of the shear walls is in terms of collapse probability. The method proposed in the Federal Emergency Management Agency (FEMA) document FEMA P695 was followed to determine the collapse levels for the high-rise structures. A nonlinear analysis was performed to analyse the failure safety of the models. Results indicate that an increase or decrease in the axial force ratios by more than 15% renders the structure either overdesigned or deficient. Doi: 10.28991/CEJ-2022-08-03-011 Full Text: PD
