Development of a framework for obsolescence resolution cost estimation
No full textCurrently, manufacturing organisations worldwide are shifting their business
models towards Product-Service Systems (PSS), which implies the
development of new support agreements such as availability-based contracts.
This transition is shifting the responsibilities for managing and resolving
obsolescence issues from the customer to the prime contractor and industry
work share partners. This new scenario has triggered a new need to estimate
the Non-Recurring Engineering (NRE) cost of resolving obsolescence issues at
the bidding stage, so it can be included in the support contract. Hence, the aim
of this research is to develop an understanding about all types of obsolescence
and develop methodologies for the estimation of NRE costs of hardware
(electronic, electrical and electromechanical (EEE) components and materials)
obsolescence that can be used at the bidding stage for support contracts in the
defence and aerospace sectors.
For the accomplishment of this aim, an extensive literature review of the related
themes to the research area was carried out. It was found that there is a lack of
methodologies for the cost estimation of obsolescence, and also a lack of
understanding on the different types of obsolescence such as materials and
software obsolescence. A systematic industrial investigation corroborated these
findings and revealed the current practice in the UK defence sector for cost
estimation at the bidding stage, obsolescence management and obsolescence
cost estimation. It facilitated the development of an understanding about
obsolescence in hardware and software. Further collaboration with experts from
more than 14 organisations enabled the iterative development of the EEEFORCE
and M-FORCE frameworks, which can be used at the bidding stage of
support contracts to estimate the NRE costs incurred during the contracted
period in resolving obsolescence issues in EEE components and materials,
respectively. These frameworks were implemented within a prototype software
platform that was applied to 13 case studies for expert validation

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

Fax: +966-1-4679493Non-missile penetrating spinal cord injuries are uncommon, and involvement of the craniocervical junction is even less frequent. The author reports a case of 42-
year-old male who presented with quadriparesis immediately following stab injury inflicted with a kitchen knife to
the back of his neck. The knife was retained in the patient’s neck. Neurological examination revealed spastic
paraplegia and severe weakness of the left upper limb and the right-hand grip, and sensory disturbance from C2 and
downwards. In addition to these symptoms, cerebrospinal fluid (CSF) was leaking from the wound. Computerised tomography (CT) scan showed the blade passed through
the spinal canal and its tip reached the odontoid peg. After retrieval of the knife, his quadriparesis recovered. The
management and outcome of the patient are described
Modeling of a Photovoltaic-Powered Electric Vehicle Charging Station with Vehicle-to-Grid Implementation
No full textThis paper is aimed at modelling of a distinct smart charging station for electric vehicles (EVs) that is suitable for DC quick EV charging while ensuring minimum stress on the power grid. Operation of the charging station is managed in such a way that it is either supplied by photovoltaic (PV) power or the power grid, and the vehicle-to-grid (V2G) is also implemented for improving the stability of the grid during peak load hours. The PV interfaced DC/DC converter and grid interfaced DC/AC bidirectional converter share a DC bus. A smooth transition of one operating mode to another demonstrates the effectiveness of the employed control strategy. Modelling and control of the different components are explained and are implemented in Simulink. Simulations illustrate the feasible behaviour of the charging station under all operating modes in terms of the four-way interaction among PV, EVs and the grid along with V2G operation. Additionally, a business model is discussed with comprehensive analysis of cost estimation for the deployment of charging facilities in a residential area. It has been recognized that EVs bring new opportunities in terms of providing regulation services and consumption flexibility by varying the recharging power at a certain time instant. The paper also discusses the potential financial incentives required to inspire EV owners for active participation in the demand response mechanism
Determination of nitrofurantoin drug in pharmaceutical formulation and biological fluids by square-wave cathodic adsorptive stripping voltammetry
No full textNitrofurnation is an antibacterial drug. It is used in the treatment of initial or recurrent urinary tract infections caused by susceptible organisms. The cyclic voltammogram of the drug in Britton-Robinson buffers (pH 2-11) exhibited a single well-defined cathodic peak at the hanging mercury drop electrode, that due to the reduction of its nitro group to the amine stage. A fully validated, sensitive, and reproducible developed procedure was described for determination of the drug in bulk form, pharmaceutical formulation, human serum and human urine using, square-wave cathodic adsorptive stripping voltammetry. The optimal experimental parameters for the drug assay were: accumulation POTENTIAL=?0.4 V (vs. Ag/AgCl/ KCls), accumulation TIME=40 s, FREQUENCY=120 Hz, pulse AMPLITUDE=50 mV and scan INCREMENT=10 mV in Britton–Robinson buffer (pH 10). A mean percentage recovery of 100.68 +/- 0.17 (n = 5) and a detection limit of 1.32 x 10(-10) M of bulk drug were achieved. Applicability to assay of the drug in pharmaceutical formulation, human serum and human urine was studied and illustrated. The mean percentage recoveries were found as: 101.49 +/- 0.65, 103.94 +/- 0.73 and 101.98 +/- 0.52 (n = 5) in pharmaceutical formulation, human serum and human urine, respectively. Detection limits of 2.86 x 10(-10) M and 5.77 x 10(-10) M nitrofurantoin were achieved in human serum and urine, respectively
