Celotna linija proizvaja trofazni električni pametni števec. Glede na potrebe stranke se proizvajajo različne vrste trofaznih števcev. Robotna celica bo sposobna sestavljati različne vrste števcev.
Robotna celica je oblikovana, ustvarjena, simulirana in preizkušena fizično in virtualno. Programska oprema, uporabljena za izvedbo tega projekta, so SOLIDWORKS, ROBTSTUDIO in TIA PORTAL/WINCC RUNTIME. Programska oprema SOLIDWORKS se uporablja za oblikovanje in modeliranje 3D-modela robotskih orodij, dozirnikov, blisterjev in pnevmatskih predalov za blisterje. Robotska orodja so fizično ustvarili s 3D-tiskalnikom, ki ga je mogoče namestiti na dejanskega robota, da preizkusi in preizkusi koncept ideje sestavljanja. ROBOTSTUDIO in TIA PORTAL se uporabljata za simulacijo in nadzorovanje robotne celice.
Trenutno je linija avtomatizirana za 42,86% s štirimi delavci, ki delajo na liniji. Po uvedbi avtomatizacije ročne delovne postaje bo avtomatiziranih 71,43% linije, pri čemer bosta na liniji delala le dva delavca.In this master thesis project, we will cover the process of transforming a complex manual assembly workstation of an electric smart meter line to an automatic assembly robot cell. The whole line is producing a three-phase electric smart meter. Based on the customer needs, different types of the three phase meters are produced. The robot cell will be able to assemble the different types of meters.
The Robot cell is designed, created, simulated, and tested physically and virtually. The softwares used to implement this project are SOLIDWORKS, ROBTSTUDIO and TIA PORTAL/WINCC RUNTIME. SOLIDWORKS software is used for designing and modeling the 3D model of the robot tools, feeders, blisters, and pneumatic drawers for the blisters. Robot tools have been created physically by a 3D printer, which can be installed on the actual robot to prove and test the concept of the idea of the assembly. ROBOTSTUDIO and TIA PORTAL are used to simulate and control the Robot cell.
Currently, the line is 42.86% automated with four workers working on the line. After implementing the automation of the manual workstation, 71.43% of the line will be automated with two workers working on the line
Adapting authoritarianism: institutions and co-optation in Egypt and Syria
No full textThis PhD thesis compares Egypt and Syria’s authoritarian political systems. While the tendency in social science political research treats Egypt and Syria as similarly authoritarian, this research emphasizes differences between the two systems with special reference to institutions and co-optation. Rather than reducibly understanding Egypt and Syria as sharing similar histories, institutional arrangements, or ascribing to the oft-repeated convention that “Syria is Egypt but 10 years behind,” this thesis focuses on how events and individual histories shaped each states current institutional strengthens and weaknesses. Specifically, it explains the how varying institutional politicization or de-politicization affects each state’s capabilities for co-opting elite and non-elite individuals.
Beginning with a theoretical framework that considers the limited utility of democratization and transition theoretical approaches, the work underscores the persistence and durability of authoritarianism. Chapter two details the politicized institutional divergence between Egypt and Syria that began in the 1970s. Chapter three and four examines how institutional politicization or de-politicization affects elite and non-elite individual co-optation in Egypt and Syria. Chapter five discusses the study’s general conclusions and theoretical implications.
This thesis’s argument is that Egypt and Syria co-opt elites and non-elites differently because of the varying degrees of institutional politicization in each governance system. Rather than view one country as more politically developed than the other, this work argues that Syria’s political institutions are more politicized than their Egyptian counterparts. Syria’s political arena is, thus, described as politicized-patrimonialism. Syria’s politicized-patrimonial arena produces uneven co-optation of elites and non-elites as they are diffused through competing institutions. Conversely, the Egyptian political arena remains highly personalized as weak institutions and individuals are manipulated and molded according to the president’s ruling clique. This is referred to as personalized-patrimonialism. As a consequence, Egypt’s political establishment demonstrates more flexibility in ad hoc altering and adapting its arena depending on the emergence of crises.
This study’s theoretical implications suggest that, contrary to modernization and democratization theory’s adage that institutions lead to a political development, politicized institutions within a patrimonial order actually hinder regime adaptation because consensus is harder to achieve and maintain. It is within this context that Egypt’s de-politicized institutional framework advantages its top political elite. In this reading of Egyptian and Syrian politics, Egypt’s personalized political arena is more adaptable than Syria’s. These conclusions do not indicate that political reform is a process underway in either state

Casing design considerations for horizontal wells
No full textHorizontal Drilling is now a well established technique with growing popularity for exploiting a number of reservoirs which would otherwise be noncommercial. However, a horizontal well requires a substantial engineering work compared to conventional directional drilling. Significant advances in drilling technology have made it possible to drill horizontally in almost any situation by using very specialized tools. But some inherent weaknesses to this technique still exist, like casing design. Most of the reported horizontal wells are completed with open hole or slotted linear. This type of completion is simple and inexpensive, but may not furnish enough support to the walls of the well to allow for long well life. This paper discusses casing design considerations for horizontal wells. It addresses the type and nature of loads applied on casing strings set in horizontal wells; examples of these loads are torque and drag, formation subsidence, effect of perforations, and bending loads. A design method for casing string under loads that prevail in horizontal wells is also included. The proposed design method shows that the horizontal section needs high collapse resistance pipe or thick-wall pipe to avoid casing failure due to non-conventional loads that prevails in horizontal wells

Resurrecting Silent Histories : A Journey through the Historical Novels of Kurdish Author Jan Dost
No full textThis article explores the historical novels of Kurdish author Jan Dost, highlighting theirrole in resurrecting and preserving the silent histories of the Kurdish people. By examining Dost’sworks through the lens of Georg Lukács’s theory of the historical novel, the article delves into howDost’s narratives blend fiction with historical events to cultivate national consciousness and reconstructKurdish identity. The study discusses the evolution of the historical novel as a genre and itssignificance in Kurdish literature, emphasizing Dost’s unique contributions. It argues that the nationalistthemes and character portrayals in Dost’s novels serve as a literary mechanism to reclaim Kurdishhistory, foster collective memory, and inspire cultural resilience. This analysis aims to understandthe reasons behind the success and literary impact of Dost’s works in the broader context ofKurdish and Middle Eastern literature
Software application for computer aided vocabulary learning in a blended learning environment
No full textThis study focuses on the effect of computer-aided vocabulary learning software called \u27ArabCAVL on students\u27 vocabulary acquisition. It was hypothesized that students who use the ArabCAVL software in blended learning environment will surpass students who use traditional vocabulary learning strategies in face-to-face learning environment even though both groups were using the same framework for introducing vocabulary. Pre-test and post-test were used for assessing the previously mentioned factors, while a questionnaire with open-ended questions was used to elicit students\u27 attitudes toward using the software. Despite the fact that both the Nation (2001) framework and the ArabCAVL software showed a significant increase in students\u27 vocabulary recognition and usage, the results of the treatment group exposed to ArabCAVL software were clearly higher than those of the control group. Finally, the results supported the previously mentioned hypothesis, and it was shown that students had a positive attitude toward the software
