Analysing Newsvendor Problems: A Cash-flow Net Present Value Approach
Cash-flow based Net Present Value (NPV) modelling in supply chain and inventorymanagement has not received much attention in the context of stochastic demand.It offers, however, an accurate approach to study the interactions between logisticsdecisions, demand pattern characteristics, and payment contract details with suppliers, and their combined effect on expected future profits. In this thesis, we examine the usefulness of this technique in the context of two-echelon supply chains in which the downstream firm (retailer) faces a newsvendor problem for each product to be sold during a selling season. In a first part, we examine the value proposition of Net D clauses. Popular opinion is that these contracts, often used in retail supply chains, hurt suppliers. Using cash-flow NPV modelling we can get insight into why this would be, and when this popular opinion is incorrect. In the second part, we show how cashflow NPV modelling helps to design so-called mixing contracts to establish perfect coordination in such supply chains. A mixing contract includes elements of discount, buyback, and revenue sharing contracts, and the increased flexibility means that the firms can also aim to achieve good performance on other criteria besides profit. In the case of information asymmetry, we show that with a dishonest firm, both parties can still benefit. In the final part, we develop an NPV model that captures non-stationary demand over a selling season and solve it with backward induction. Firms could benefit from this approach to help exploit their knowledge about product sales variations during the normal selling period, and/or about the conditions for selling during a discount/sales period
An investigation framework for the Internet of Things (IoT) forensics
Recently, the usage of the Internet of Things (IoT) technology has rapidly increased. Smart devices are used in major domains including healthcare, transportation, agriculture and residential. Even though there are billions of devices available on the market, IoT devices are still immature. With the IoT constraints and low-security feature, devices could easily be attacked, treated and exploited by cybercriminals. This may cause the devices to provide wrong data leading to wrong interpretation and actuation to the legitimate users. Since the number of incidents related to IoT devices is alarming, a new digital forensic framework is needed to handle crimes related to the IoT. Therefore, this thesis addresses the requirement to develop a conceptual framework to support IoT forensics investigation. The main contribution of this research is the development of the IoT forensics investigation framework to support an integrative approach to understanding and evaluating the nature of the IoT components and forensics requirements to run investigations. The framework enables us to understand the needs of security factors in IoT devices and the requirement of the investigation process. Based on theories and prior research findings, the framework indicates that the security of the IoT devices is determined by five factors: (1) Authentication, (2) Availability, (3) Integrity, (4) Confidentiality, and (5) Access Control. Meanwhile, the forensic investigation is determined by three main phases: (1) Pre-investigation; (2) Investigation and (3) Post-Investigation. Deriving from the IoT forensics investigation framework, the pre-investigation phase has been emphasised and evolved through the development of a Readiness Instrument. The instrument measures the stakeholder’s readiness to conduct an IoT forensic investigation. There are six readiness factors measured: (1) Capability of the organisation, (2) Strategic Planning, (3) Resources, (4) Operability, (5) Knowledge of IoT and (6) Awareness IoT. After a series of experiments, the instrument has been validated and used in a research scenario. A Goal-Question-Metric (GQM) approach is used to generate the items in the instruments. The potential item was then being evaluated by a series of experiments: (1) pre-test and (2) the validation study. In the pre-test, the items were assessed using content validity ratio by digital forensic experts. After that, the validation study completed two experiments that investigated the correlation analyses and internal reliability. A part of the development of the investigation framework and readiness instrument, the IoT Vulnerability table has also been established to help the investigator in the pre-investigation phase. The table lists the components of each IoT entity and common threats that attack IoT devices. The IoT vulnerability table can be used as guideline for the investigator to run the preliminary investigation. The table has been validated by digital experts and used in a research scenario. The readiness instrument and the IoT vulnerability table were later applied in three IoT crime cases to test the practicality of both contributions. The validated instrument and table were sent to the digital forensic experts for assessment, before the interview was held. The findings revealed that both tested instrument and table have achieved good impact in usability and user acceptance. Therefore, the instrument has been recommended by experts for implementation in the pre-investigation as they need to prepare before conducting the IoT forensic investigation. With the guide from the IoT vulnerability table, it can reduce investigation time and helps the investigator to narrow down the scope of investigation during the preliminary stage. This thesis presents a detailed discussion on the development and validation of the IoT forensic investigation framework, readiness instrument and, the IoT vulnerability table. These contributions have shown significant impact in the forensic field specifically in the IoT context. For the management level, the instrument has highlighted readiness issues that need to be considered in their organisation and preparation to be forensically ready to run the IoT forensic investigation. At the operational level, people need to have a knowledge and awareness of the nature of IoT before handling IoT crime cases. The guide table enables the investigator to focus and run the investigation effectively. For the researcher, the framework, readiness instrument and, IoT vulnerability table helps to conceptualise their research and use it as a basis for further investigation in the future

Thermal analysis of composite materials for roofing / Azuddin Zulkipli
Composite materials are desirable in many industrial applications, including manufacturing, construction, machinery and appliances. Improvements can be made on the heat transfer properties of composite materials if experiments are conducted on its thermal properties. In this project, we made a research on thermal properties of a composite material designed for roofing, which is being used in many mosques in the country such as the mosque of Sultan Sallahuddin Abdul Aziz Shah, Shah Alam and Wilayah Persekutuan Mosque, in Kuala Lumpur. With this investigation, we will be able to analyze the thermal properties, particularly the heat transfer and thermal conductivity of the dome composites and investigate about its appropriateness as a roofing material for use in tropical climates. The company that has provided the samples of the composites is a local manufacturing company called Dian Kreatif Sdn Bhd, located in Malacca. Up to date, the company has constructed at least 55 domes used for mosques throughout the world, including the Prophet Mosque in Medina and the Putrajaya Mosque and also 22 boats. Tests were conducted on several separate samples as well as samples of different combinations of the composites using the thermal conductivity apparatus. Air temperatures and surface temperatures were taken in the interior and exterior of square models of the dome placed in a solar radiation simulator used as a heat source. Both the thermal conductivity apparatus and the solar radiation simulator are situated at the Mechanical Engineering Faculty of Universiti Kebangsaan Malaysia. Preliminary results show that the composite materials, together with its strength and durability can be appropriately used as roofing materials. However, further studies will have to be conducted on its cost effectiveness and feasibility as composites are very expensive
Fatigue strength of bolts / Mohd Zulkipli Abdul Majid
Fatigue of metals have been studied for the past 150 years but still many uncertainties have not been explored. Despite all the knowledge available nowadays fatigue failure still continue to occur especially in engineering and building construction. The extensive use of metals such as steel in the construction industries and many metal fatigue failure occurrence have lead researchers to focus their studies on the fatigue strength of metal. Bolts are widely used in many types of construction in jointing members of a structure. Thus the study of its fatigue strength are of vital importance. This experimental study carried out was to determine the fatigue strength of 12 mm diameter High Strength Friction Grip (HSFG) bolt under repeated tensile loading (cyclic loading). Using the stress- life ( S-N method) the metal specimens were being subjected to a stress within the elastic range of the material. The effect of fatigue parameter, the mean stress and stress range influence on the resultant lives (cycles to failure) of the bolts are studied based on a design monograph known as the S-N curve. Various test have been carried out in the laboratory namely the Static Tensile Test, Fatigue Sensitivity Test and the Fatigue Test using a special machines that was design to perform this test. From this experiments fatigue characteristic and fatigue strength can be observed

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
