The implications of social media marketing towards enhancing brand loyalty / Muhammad Faheem Abdul Majid and Niftahul Janna Hussin
Full text linkResearch have demonstrated that there are a few variables that impact a client's choice to repurchase an item or benefit or to be faithful to be a specific item. . Lau et al. (2006) in his article said that there were a few components that affected buyers' image steadfastness towards certain brands. The variables were brand name, item quality, value, and advancement and administration quality. Other scientist have likewise thought of variables that impact brand dedication and one thing stays basic with them where they trust that item quality or saw item quality assumes a part in client brand devotion. In any case, an audit of writing on the relationship between item quality and brand unwaveringness has highlighted the hole in writing that basically breaks down the item quality and brand reliability build or the level of impact that item quality has on brand devotion.
The current writing in regards to online networking is genuinely later and basically concentrates on the open doors and advantages of engagement between the buyer and the brand. By comprehension and using online networking showcasing, knowing the desires of social networking shoppers, and making trusting associations with those customers, social networking can be connected to any neighborhood business or expansive partnership to build purchaser steadfastness. Online networking has permitted clients to discuss what they need, need, as, and don't care for continuously, making an open door for organizations to take advantage of this information and interface on an individual level ("Strategic Direction," 2012, p.25). Since online networking is being used at an undeniably quick pace by purchasers, it is basic to direct research on the ebb and flow methodologies utilized by experts as a part of showcasing and advertising by gathering master suppositions on the subject of social networking advertisement.
Inside the previous couple of years, online networking has turned into an inexorably mainstream medium for brand and shopper engagement. "The intuitive way of online networking (its capacity to build up discussions among people, firms in groups of merchants and clients, and include clients in substance era and worth creation) has energized experts with its capability to better serve clients and fulfill their necessities" (Sashi, 2012, p. 254). For quite a long time, advertising and showcasing experts have utilized diverse mediums to give client benefit and advance items. Online networking has cultivated the development of trusting connections amongst customer and brand, making it an inexorably imperative medium to use with a specific end goal to boost brand faithfulness.
The researcher doing this exploration to perceive how the online networking can give an effect to the brand dependability. Since, the rise of neighborhood business visionary, for example, D'herbs, Sendayu Tinggi, Vida Beauty, Nouvelles Visages and numerous more made excessively numerous beautifying agents and healthy skin item sold in Malaysia. In this manner, they have to rival worldwide brand. Corrective has turned into a typical and prominent classification among youthful and grown-up individuals these days. This is on account of individuals now more worry about their look. In this globalization time, business visionary can take these chances to expand their image faithfulness through online networking
MQRP: Mobile sinks-based QoS-aware data gathering protocol for wireless sensor networks-based smart grid applications in the context of industry 4.0-based on internet of things
No full textPhd, Muhammad Faheem,/0000-0003-4628-4486The recent advances in internet of things (IoT) and industrial wireless sensor networks (IWSNs) paradigm provide a promising opportunity for upgrading todays elderly electricity industrial systems and even allow the fourth stage of the industrial revolution, referred to as smart grid industry (SGI) 4.0. In SGI 4.0 paradigm, the WSNs are considered as promising solutions due to their advantages, such as cable replacement, ease of deployment, flexibility, and cost reduction. However, harsh and complex smart grid (SG) environments pose great challenges to guarantee reliable communication for WSNs-based SG applications due to equipment noise, electromagnetic interference, multipath effects and fading in SG environments. This results in deteriorating the quality-of-service (QoS) requirements as well as the network lifetime of multi-hop communication-based WSNs for SG applications. Thus, for SGI 4.0 paradigm to come true, a WSN-based highly reliable communication infrastructure is crucial that will wirelessly connect and integrate power system components for more efficient, reliable, and intelligent operations of the next-generation electricity power grids. To address these challenges, in this paper a novel multi-mobile sinks-based QoS-aware data gathering protocol (called MQRP) for WSNs-based SG applications has been proposed to empower SGI 4.0. The extensive simulations study is carried through a network simulation tool called EstiNet9.0. The obtained experimental facts show that the proposed scheme has not only improved the QoS performance metrics, such as packet delivery ratio, memory utilization, control message overhead, residual energy, network lifetime, and throughput, but also reduced packet error rate and end-to-end delay compared to existing data collection schemes.

Physical Layer Security for In-Body Wireless Cardiac Sensor Network
Full text linkThe thesis explores the physical layer security approaches for securing an in body multi-nodal leadless cardiac pacemaker (LCP) communication system. Pacemakers are implanted medical devices, used to treat different types of cardiac arrhythmias. The widely used version of these pacemakers is implanted with intravascular leads. Due to lead related complications, the next generation of pacemaker systems are becoming wireless i.e., connecting multiple nodes wirelessly without intravascular leads.
Besides the unquestionable benefits of LCPs such as less invasive surgery, there are also some concerns associated with it. The wireless nature of these devices is a significant security risk and could lead to threats like eavesdropping, data tampering, and device modification.
This thesis deals with the problem of quantifying the severity of risks associated with the wireless nature of these next generation LCPs and the corresponding countermeasures by utilizing the physical layer security (PLS) techniques.
To evaluate the system eavesdropping risk without PLS, we use the concept of communication link outage probability. A link is said to be in an outage if the received signal to noise (SNR) ratio falls below the threshold required for error free decoding. We compute the eavesdropper (Eve) link outage probability for evaluation of eavesdropping risk with respect to the distance around the body. Similarly, for developing the corresponding countermeasures, we explore two different approaches of PLS for securing LCP. The first approach provides a secure communication strategy via channel modeling and offers data secrecy and reliability simultaneously, without use of data encryption. The second approach provides an alternative for symmetric key generation between legitimate nodes and avoids the use of key management and distribution servers as in the case of conventional cryptographic methods.
For channel modeling strategy, our hypothesis is on the availability of positive secrecy capacity in the close proximity of the human body. Secrecy capacity is the performance metric that supports secrecy and reliability at the same time and is the maximum attainable secure communication rate without leakage of information to Eve. Secrecy capacity depends on the inherent noise within the wireless channels.
To implement a channel modeling approach, prior knowledge about wireless channels is required and can only be implemented when the legitimate nodes have superior channel quality over Eve on the physical layer.
To evaluate the secrecy capacity, the methodology of electromagnetic simulations and experimental measurements is adopted for modeling the in-body to in-body (legitimate) and in-body to off-body (Eve) wireless channels. The results show that the positive secrecy capacity is achievable within the human personal space of 25 cm, with practical antenna realizations. Furthermore, to examine the effect of electromagnetic radiations through the human body across different angles in three dimensional space, the spatial secrecy capacity is also evaluated. The angle from which the maximum leakage of information takes place is found to the left from front, just above the heart and is termed as the “Eve sweet spot angle”. Eve’s sweet spot angle has the least secrecy capacity among all the eavesdropper spatial positions with the human heart as a reference position. The results proved our hypothesis that the human body as a lossy medium for electromagnetic propagation inherently provides high attenuation to off-body Eve link, thus offering legitimate nodes an advantage on the physical layer for implementation of channel modeling approach.
For solving the issues related to key management and distribution in case of traditional cryptographic algorithms, the dissertation also explores the source modeling approach to establish symmetric keys between legitimate nodes. The source modeling approach exploit the correlated information source between legitimate nodes for key generation. We hypothesized that the electromagnetic reflections experienced due to in-body transmissions provide enough randomness to generate a symmetric key from wireless parameters like received signal strength (RSS), phase, angle of arrival, etc. Therefore, we generated a symmetric key string between the in-body nodes by utilizing the randomness in the RSS measurements. Similarly, due to the availability of inherent physiological signals, the feasibility of symmetric group key establishment across multiple nodes of the leadless pacemaker system is also analyzed. Both methods provide viable alternatives with RSS based key generation method outperforming the other with a bit mismatch rate of approximately 1%
Homeobox leucine zipper proteins and cotton improvement
No full textTranscription factors play key roles in plant develop- ment and stress responses through their interaction with cis-elements and/or other transcription factors. Homeodomain associated leucine zipper proteins (HD-Zip) constitute a family of transcription factors that are characterized by the presence of a DNA- binding domain closely linked with leucine zipper motif functioning in dimer formation. This type of association is unique to plants and considered as an excellent candidate to activate developmental respons- es to altering environmental conditions. Cotton is the most important fiber plant with a lot of local and commercial uses in the world. HD-Zip proteins not only have key roles in different stages of vascular and inter-fascicular fiber differentiation of cotton but also are suggested to have an important role against abio- tic stress that is one of the key factors limiting cotton productivity. Plants have developed various strategies to manage stress conditions through a combination of metabolic, physiological and morphological adapta- tions. These adaptive changes rely largely on altera- tions in gene expression. Therefore, transcriptional regulators play a crucial role in stress tolerance. Be- ing a transcription factor HD-Zip might be a useful target for genetic engineering to generate multiple stress tolerance in susceptible plants. In the following chapter, we discussed how the HD-Zip proteins would play a useful role for cotton development both in fiber production and stress adaptation.Open-Access-Publikationsfonds 201
Developing Heat Transfer for Laminar Flow of Power-law Fluids in the Entrance Region of a Pipe
No full textA Master of Science thesis in Chemical Engineering by Muhammad Faheem Hassan entitled, “Developing Heat Transfer for Laminar Flow of Power-law Fluids in the Entrance Region of a Pipe”, submitted in June 2022. Thesis advisor is Dr. Rachid Chebbi. Soft copy is available (Thesis, Completion Certificate, Approval Signatures, and AUS Archives Consent Form).The objective of this thesis is to develop a model to solve the combined hydrodynamic-thermal entrance region problem for laminar flow of power-law fluids in a circular pipe under uniform wall heat flux condition. The model is based on the inlet-filled region concept of Ishizawa (1966) and uses a boundary layer integral method to solve for the simultaneously developing velocity and thermal profiles. The developed model for power-law fluids uses the hydrodynamic entrance region model developed by Chebbi (2002) for power-law fluids and extends the heat transfer model presented by Al-Ali (1988), and Al-Ali and Selim (1992) for the Newtonian fluid flow case. The axial location at which the thermal boundary layer thickness reaches the circular pipe radius value represents the end of the thermal inlet region. The local Nusselt number asymptotically approaches the fully developed value. The solution is performed in each of the three zones forming the thermal entrance region: hydrodynamic inlet-thermal inlet, hydrodynamic filled-thermal inlet and hydrodynamic filled-thermally filled regions. The local Nusselt number variations along the axial distance of the pipe for power-law indices n = 0.6, 1 and 1.4 and Prandtl number, Pr = 1, 5, 10 and 15 are presented graphically and in tabulated forms. The dimensionless thermal entrance region length is calculated using a Nusselt number criterion (local Nusselt number equal to 1.05 the asymptotic value). Its values at Pr = 5 and for n = 0.6, 1 and 1.4 are 0.3222, 0.3532 and 0.3831, respectively. The Nusselt number asymptotic values for n = 0.6, 1 and 1.4 are 4.49, 4.36 and 4.30, respectively. The present results are in good agreement with the theoretical results in the literature for n=1 (Newtonian fluid case). To my knowledge, no experimental data, numerical or theoretical results asymptotically matching the fully developed solution, are available for the case of simultaneously developing fluid flow and heat transfer for power-law fluid flow in pipes.College of EngineeringDepartment of Chemical EngineeringMaster of Science in Chemical Engineering (MSChE

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
Key generation technique based on triangular coordinate extraction for hybrid cubes
No full textCryptographic algorithms play an important role
in information security where it ensures the security of data
across the network or storage. The generation of Hybrid Cubes
(HC) based on permutation and combination of integer numbers
are utilized in the construction of encryption and decryption key
in the non-binary block cipher. In this study, we extend the
hybrid cube encryption algorithm (HiSea) and our earlier
Triangular Coordinate Extraction (TCE) technique for HC by
increasing the complexity in the mathematical approaches. We
proposed a new key generation technique based on TCE for the
security of data. In this regard, the Hybrid Cube surface (HCs)
is divided into four quarters by the intersection of primary and
secondary diagonal and each quarter is rotated by using the
rotation points. The overall security of HC is improved by the
rotation of HCs and enhanced the complexity in the design of
key schedule algorithm. The brute force and entropy test are
applied in experimental results which proved that the proposed
technique is suitable for implementing a key generation
technique and free from any predicted keys pattern
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
