description: A topological superconductor (TSC) is characterized by the topologically-protected gapless surface state that is essentially an Andreev bound state consisting of Majorana fermions. While a TSC has not yet been discovered, the doped topological insulator CuxBi2Se3, which superconducts below ~3 K, has been predicted to possess a topological superconducting state. We report that the point-contact spectra on the cleaved surface of superconducting CuxBi2Se3 present a zero-bias conductance peak (ZBCP) which signifies unconventional superconductivity. Theoretical considerations of all possible superconducting states help us conclude that this ZBCP is due to Majorana Fermions and gives evidence for a topological superconductivity in CuxBi2Se3. In addition, we found an unusual pseudogap that develops below ~20 K and coexists with the topological superconducting state.

description: Australian courts have held that the COVID-19 pandemic should impact on the nature and severity of criminal sanctions. Broadly, it has been argued that prisoners are more likely to be infected with COVID-19, to experience adverse outcomes because of existing compromised health conditions, and to experience more onerous incarceration due to lengthy periods in lockdown. The courts, on balance, have been sympathetic to these and other arguments, and accordingly have been willing to extend a sentence discount as a result of the pandemic. This article argues that while there is some theoretical support for this approach, it is inconsistent with the weight of established jurisprudence that strictly interprets the circumstances in which a penalty reduction will be accorded for health reasons. The judicial approach to factoring COVID-19 into the sentencing calculus provides the opportunity for broader analysis of the manner in which medical conditions and strict prison conditions should be weighed as relevant factors in sentencing outcomes. The pandemic has also raised the potential use of remissions through executive action as another form of sentence discount for prisoners. The reforms ultimately proposed will make this area of sentencing law more doctrinally coherent and lead to more consistent and predictable outcomes.

description: Undifferentiated pleomorphic sarcoma (UPS) is one of the most common, aggressive, and metastatic soft tissue sarcomas in adults. Generally, UPS are unresponsive to conventional chemotherapies or immunotherapies, which is believed to be attributed to the immunosuppressive tumor microenvironment (TME) of these malignancies. Preclinical studies in the murine KP model of UPS showed that intratumoral (i.t.) activation of the STimulator of INterferon Genes (STING) pathway using the murine STING agonist DMXAA, elicited immune mediated UPS clearance in 50-75% of treated mice. To assess the translational potential of STING immunotherapy, I tested the anti-tumor efficacy of three STING agonists in the KP model of UPS capable of activating both human and murine STING. Excitingly, E7766 emerged as a translational STING agonist which can shift the UPS TME towards an immunologically inflamed phenotype. Thirty-eight percent of E7766 treated mice eradicated their primary tumors which was CD8+ T-cell dependent. Of the mice that eradicated primary UPS tumors, 87.5% develop protective immunity against UPS re-challenge. Next, I investigated which cell types in the UPS TME engage in STING signaling following therapy. I found that STING expression in non-malignant host cells and not UPS cells is required to observe tumor eradication following STING immunotherapy. Single cell RNA sequencing of UPS tumors revealed that neutrophils are abundant cells in the TMEs of UPS tumors treated with DMXAA and E7766 at both timepoints. Myeloid cells were identified as the cell type with the highest interferon stimulated gene (ISG) score. Both DMXAA and E7766 maintain higher ISG scores in myeloid and lymphoid cells relative to control and CDN at the 1-week timepoint. Finally, I developed a novel gene therapy tool to explore forced expression of the constitutively active mutant hSTINGN154S protein using plasmid DNA. Using these tools, I transfected TAO1 UPS and HEK293T cells and confirmed the functional status of the hSTINGN154S protein’s expression in vitro. In summary, these data suggest that E7766 is an exciting therapeutic candidate for UPS, and further investigation into the importance and consequences of STING signaling in various UPS TME cell types is required to understand therapeutic mechanisms of this therapy.

We also extend some known results on the diagonal and the off-diagonal Fibonacci Hamiltonians.

description: This thesis presents insights from a year-long co-design study with frontline staff at an emergency housing shelter in Canada: The Calgary Drop-In Centre. The homelessness sector encounters high rates of staff turnover due to mental health issues. If these issues interrupt important frontline work, vulnerable clients could miss the opportunity to escape homelessness. While prior research in HCI focuses on designing technology to be used by those experiencing homelessness, I focus on how to design tools to support the frontline staff at emergency shelters. As part of their program-delivery, staff at the Drop-In Centre hold weekly meetings to decide how to move forward with clients who have threatened shelter safety. These discussions are strenuous as staff must consider all aspects of the incident to make a fair decision. During these meetings, staff navigate through an abundance of data about each interaction clients have with the shelter. Navigating through this large volume of data is burdensome, especially since making these decisions already bears a high cognitive and emotional load. Therefore, I collaborated with the Drop-In Centre to co-design and deploy an interactive data-navigation interface for these collaborative decision-making meetings about vulnerable clients. While co-designing the new tool, a design ethnography methodology was employed to understand the role that data and technology play in decision-making, and identify takeaways for future work. From June, 2022, to November, 2023, I conducted one-on-one interviews with staff, facilitated group co-design workshops, engaged in field observations, and elicited feedback on three iterations of the tool. Reflexive thematic analysis was employed to generated themes regarding how staff experience the tool, and their perceived benefits and challenges of using data to make high-stakes decisions about clients. Based on these themes, I articulate high-level design implications. This work emphasizes the need for designers and HCI researchers to consider (1) the degree to which users are willing to outsource their decision-making processes to data, and (2) users' differing preferences for rich, granular data, compared to abstracted visualizations and aggregate measures. The insights gained from this work are transferable to other human-centred organizations where staff make high-stakes, data-driven decisions about their clients.

description: Wind turbine blades experience fatigue loads resulting from cyclic loading conditions during its operation. Damage caused by fatigue loads poses a threat to the integrity of the wind turbine structure thus, it is critical to accurately predict the effect of damage progression on the remaining life of the blade. As it is the case with most composite material structures, a multiscale modelling approach is required when designing a fatigue methodology for wind turbines. Coupled models at different geometric scales have been used to understand how the operational response of the entire wind turbine system is affected by damage in the composite blades. However these methodologies employ high-fidelity damage models that are time and computationally intensive. Furthermore, most models that predict the blade’s lifetime rely on macroscopic damage models that do not consider the physical damage mechanisms. The macroscopic models produce a very conservative estimate of the fatigue life of the blades. Damage mechanics models which capture the stiffness degradation of the damaged blade in terms of a physical damage parameter such as matrix cracking can be incorporated within a multiscale framework. This type of model can capture the effects of the damaged blade on the entire wind turbine system to estimate the fatigue life with increased accuracy. This study aims to improve the current multiscale methodology by incorporating a damage mechanics model which accounts for matrix crack evolution under cyclic loading. The damage mechanics model implemented and presented in this thesis, is implemented based on a 2D finite element cross-section analysis in which the entire blade is modelled as a beam composed of several cross-sections. The material response and the structural response was analysed as damage progresses. This multiscale methodology which includes coupling with an aeroelastic analysis software, HAWC2, can be used to predict the structural response of the blades subjected to damage. The proposed method can also reduce the reliance on high-fidelity damage models to calculate the fatigue life due to damage, thus resulting in a more efficient approach.
An efficient iterative method to reduce eccentricity in numerical-relativity simulations of compact binary inspiral

description: We present a new iterative method to reduce eccentricity in black-hole-binary simulations. Given a good first estimate of low-eccentricity starting momenta, we evolve puncture initial data for ~4 orbits and construct improved initial parameters by comparing the inspiral with post-Newtonian calculations. Our method is the first to be applied directly to the gravitational-wave (GW) signal, rather than the orbital motion. The GW signal is in general less contaminated by gauge effects, which, in moving-puncture simulations, limit orbital-motion-based measurements of the eccentricity to an uncertainty of $Δe \sim 0.002$, making it difficult to reduce the eccentricity below this value. Our new method can reach eccentricities below $10^{-3}$ in one or two iteration steps; we find that this is well below the requirements for GW astronomy in the advanced detector era. Our method can be readily adapted to any compact-binary simulation with GW emission, including black-hole-binary simulations that use alternative approaches, and neutron-star-binary simulations. We also comment on the differences in eccentricity estimates based on the strain $h$, and the Newman-Penrose scalar $Ψ_4$.

description: Shallow dimples have long been a scientifically investigated topic to reduce the flow resistance of objects subjectedto overflow.  Most of the investigations on the influence of dimples on flow resistance have so far been carriedout experimentally.  Although the arrangements and flow conditions are often similar, different research activitiesconclude differently concerning the effect of the surface structures. This also leads to disagreement regarding thecauses of flow resistance reductions. In this paper, time-resolved Large Eddy Simulations on two different, alreadyexperimentally investigated setups of dimples have been carried out to better understand the effects of dimpleson the surface being subjected to relative fluid motion.  In one case the dimples were examined in overlappingarrangement, in the other case in a non-overlapping arrangement.  We were able to show that the formation ofstreaks near the surface significantly influences the local contribution to the flow resistance.  For the overlappingarrangement, only a slight resistance reduction of 0.12 % was determined. For the non-overlapping arrangement,the mean resistance reduction was found to be 3.16 %. Regardless of the resistance reduction determined, a clearinteraction between longitudinal vortices near the plate and local contributions to flow resistance could be demon-strated.  Since these longitudinal vortices are directly influenced by the dimples, it is very likely that an optimizedarrangement of the dimples, adapted to the flow conditions, can reduce the resistance.
New Conjugated Materials for Clean Energy Applications
Creators: name: Atkinson, Colton
Publisher: name: Graduate Studies
Year: 2024
Subjects: subject: Chemistry--Organic

description: This thesis details the synthesis, characterization, and applications of asphaltene model compounds for use in green energy technologies. Chapter 1 introduces green energy technologies and the current state-of-the-art organic semiconductors currently utilized in the field, as well as the concept of the asphaltene class of molecules and how they can be utilized to inspire the design of novel organic semiconductors. Chapter 2 discusses the synthetic attempts to develop a hole-transporting material on the asphaltene-derived 5,7-dihydroindolo[2,3-b]carbazole platform. While the synthesis of the building block, albeit atom-inefficient, was successful, the work presented in this chapter remains incomplete due to reactivity challenges in cross coupling reactions as well as challenging purification and characterization of the more successfully synthesized target molecules. Moving forward, Chapter 3 delves into the use of aromatic fluorination as a strategy to enhance the processability of electron-transporting materials for use in printed organic photovoltaic devices with the F-PDIN-EH compound. The F-PDIN-EH material was characterized by UV-Visible spectroscopy and cyclic voltammetry, which confirm the maintenance of the desirable electronic structure of non-fluorinated PDIN-EH for photovoltaic applications, as well as solubility measurements to probe the hypothesized change in processability, indicating upwards of nearly 10-fold enhancements to solubility. Finally, in Chapter 4, the focus shifts towards the use of asphaltene-inspired conjugated aromatics for use as lithium-ion capture agents. Simple aryl anhydrides were functionalized through condensation reactions with amino-benzo-9-crown-3 to efficiently generate aryl imides showing selective lithium-ion capture and release. Importantly, this chapter demonstrates that the conjugated backbone can be further functionalized without having an impact on the ability of the crown ether moiety to selectively capture lithium from aqueous solutions such as brine waters.

description: In this paper we establish an estimate for the rate of convergence of the Krasnosel'ski\vı-Mann iteration for computing fixed points of non-expansive maps. Our main result settles the Baillon-Bruck conjecture [3] on the asymptotic regularity of this iteration. The proof proceeds by establishing a connection between these iterates and a stochastic process involving sums of non-homogeneous Bernoulli trials. We also exploit a new Hoeffding-type inequality to majorize the expected value of a convex function of these sums using Poisson distributions.

description: It has been recently argued that the Lorentz force is incompatible with Special Relativity and should be amended in the presence of magnetization and polarization in order to avoid a paradox involving a magnet in the presence of an electric field. Here we stress the well-known fact among relativists that such an incompatibility is simply impossible and show that the appearance of such a "paradox" is a mere consequence of not fully considering the relativistic consequences of the covariant form of the Lorentz force. It should be mentioned, though, that this criticism does not invalidate the debate on which is the law of force followed by Nature, which is an experimental issue.

description: Laws are institutions that, when developed naturally, spring from the codification of existing culture. When the laws of one nation are artificially transplanted to another nation, it is a de facto imposition of an incompatible culture, and the enforcement of those laws becomes highly unlikely. These observations are invaluable, not only because they contribute to our understanding of legal development in Africa, but because such theories can also be used to explain why conditional aid is a particularly ineffective form of aid.

description: Background: This study explores the nuanced phenomenon of student resistance to social justice education, aiming to understand how and why students may resist this in the context of a new undergraduate medical curriculum at the University of Calgary. This curriculum features a longitudinal integration of a health equity and structural competency curriculum. Previous resistance from students towards this aspect of the curriculum hinted at this being a possible phenomenon in the new curriculum, thus warranting empirical investigation. Methods: This qualitative case study utilized semi-structured interviews with first-year medical students and faculty members at the University of Calgary to gain insight into student resistance and the ways it manifests. Phenomenography was used as a supplemental analytic lens to examine variation in resistance as a phenomenon. Results: Between September and December 2023, 23 semi-structured interviews were conducted with medical students and faculty members. Student resistance manifested in various emotional, cognitive, and behavioural responses. Reasons for student resistance also varied from feelings of discomfort and guilt, fear of being called out, anxiety surrounding medical knowledge and clinical competence, and personal biases and prejudice. Based on these findings, an outcome space delineates a spectrum of student resistance. Conclusion: Resistance to social justice education from medical students is a complex phenomenon that requires careful consideration. Findings from this case study reveal the diverse ways students may resist social justice education, ranging from emotional discomfort to skepticism about the relevance of social justice education to clinical practice. The findings also highlight the importance of taking proactive measures in addressing this resistance. Medical schools can work towards this by meaningfully integrating social justice education into curricula, utilizing pedagogical approaches that could mitigate potential resistance, prioritizing faculty development, and diversifying assessment strategies.
Inhibition of castration resistant prostate cancer by sintokamide A : an antagonist of the amino-terminus of the androgen receptor
Creators: name: Tavakoli, Iran
Publisher: name: University of British Columbia
Year: 2013

description: The majority of lethal castration resistant prostate cancer(CRPC)is considered to involve a transcriptionally active androgen receptor (AR). All current therapies target AR ligand-binding domain (LBD) to inhibit receptor activity. Unfortunately these therapies fail perhaps b mechanisms involving expression of constitutively active AR splice variants that lack LBD and/or de nove androgen synthesis. Recent studies have provided evidence that R N-terminus domain (NTD is druggable with the development of EPI-OO1, antagonist that has specificity and efficacy on CRPC xenografts. Here we reveal an unrelated class of compounds, SINT1 as potent therapeutic agent fr CRPC that targets NTD. To examine the effects of SINT1 on AR transcriptional activity, endogenous gene expression and reporter constructs regulated by AR were examined. The ability of SINT1 to directly inhibit transactivation of the NTD was tested using a chimera of NTD fused to the GA14DBD. Reporter assays for glucocorticoid (GR) and progesterone receptor (PR) were measured to ensure specificity. Combination study of SINT1 and EPI-002 was performed by measuring AR transcriptional activity. BrdU incorporation was analyzed to indicate changes in proliferation. Effect of SINT1 on AR N/C interaction was assessed using a 2-hybrid assay. Animals bearing LNCaP xenografts were castrated and randomized into two groups. One week after castration, the animals were treated every 3 days with an intratumoral dose of aSINT1 (30 MG/KG) or vehicle. SINT1: blocked AR activity as measured by reduction in PSA mRNA and reporter activity induced by androgen; reduced transactivation of AR NTD to baseline levels; had no effects on transcriptional activities of related steroid receptors; was effective in blocking androgen-induced proliferation in LNCaP cells but not PC3 cells; caused an increase in caspase-3/7 activity; showed an additive inhibitory effect to EPI-002; reduced AR N/C interactive; regressed some CRPC xenografts with no change in animal body weight compared to DMSO-treated tumors. Together these data support that SINT1 is a specific inhibitor of the AR NTD without effects on highly related steroid hormone receptors and no apparent toxicity in animals. SINT1 is an antagonist to AR NTD that causes regression of CRPC xenografts.

description: Widespread scientific consensus exists that the world’s climate is changing, with a majority of scientists in agreement that anthropogenic climate change is having increasingly adverse effects on human health (National Aeronautics and Space Administration [NASA] Global Climate Change, 2018; U.S. Global Change Research Program [USGCRP], 2017). Some of these changes include rising temperatures, more variable weather, heat waves, heavy precipitation events, flooding, droughts, more intense storms, sea level rise, and air pollution. Each of these impacts is currently or has the potential to negatively affect population health. While climate change is a global issue, the effects of climate change will vary across geographical regions and populations (Centers for Disease Control and Prevention [CDC], 2017a). The influence of climate change on human health appears in scientific, environmental, and public health literature, and, in more recent years, a growing discussion and advocacy for personal and professional response are present in the nursing literature. This chapter provides an overview of the influence of climate change on health, along with a selection of key findings from surveys exploring nurses’ knowledge, beliefs, and challenges in responding to climate change. A wide range of ongoing activities at various practice settings offers resources for further study and action opportunities for nurses and their healthcare partners.

description: This thesis argues that an evolved version of the literary genre, petrofiction, would improve how citizens of hydrocarbon-extracting communities understand the linkages between oil and life’s abstractions in the current decade and enhance energy literacy, more broadly. This, in turn, would promote more productive public conversation around transitioning to a low carbon future in Canada. A sample of five texts are close read in order to analyze petrofiction conventions over the past century. The primary conclusion of this analysis is that the women leaders of the present are not represented in petrofiction; consequently, the creative portion which resolves this void offers a model for an evolved petro-novel. Energetic is a novel about two Alberta characters over the course of four months. When the story begins, Barbara Warren and Antoinette “Tony” Nailer are strangers, each employed in different parts of the petroleum sector. A catastrophic event at an oil sands upgrader brings them together as antagonists. This story is set in the current moment of ecological and economic upheaval, in the initial phase of our transition from the world’s heavy dependency on oil in order to underscore the pace of technological progress, the impact of government policy, the role of the media, and the weight of personal and corporate decision-making today. It is inspired by history being written, in real-time, by the promises and actions of Albertans working in the sector. This novel subverts the limited and skewed record of this history as documented by polished corporate literature, inconsistent media coverage, and fleeting social platform posts. Energetic’s narrative unpacks the business tools available today and the current barriers or opportunities to act. Unlike the evil oilman trope common to petrofiction texts, the two female protagonists in this story engage with industry challenges while maintaining a personal distance from the threatening effects of oil extraction. Competition, ego, and greed do not form the motivational foundation of these two business leaders. This novel interrogates the economic and social conditions that shape responses to a demand for transition from the unique perspective of Albertans, a population residing in proximity to natural resource extraction activity, and a population seeking nuanced energy-literate conversations.

description: Background: Parental mental health concerns are common during the first few years following childbirth and are associated with adverse consequences for mothers and their children. The COVID-19 pandemic contributed to elevated levels of maternal mental health problems and introduced unique parenting stressors, highlighting the urgent need for accessible digital mental health interventions. There is a robust association between the quality of romantic relationships and psychopathology, and romantic relationship quality can influence the effectiveness of individual mental health interventions. Therefore, the current dissertation 1) evaluated the preliminary effectiveness and feasibility of a novel app-based program for mothers of infants and toddlers presenting with depression and/or anxiety (BEAM), 2) discussed program revisions, and 3) assessed the association between relationship factors and treatment effectiveness. Methods: The first manuscript was a pilot study of the BEAM program. The transition chapter discusses adaptations to the BEAM program and observations from the initial study that helped to inform the second manuscript. The second manuscript examined relationship factors as moderators of treatment outcomes using a phase-III longitudinal RCT. Results: The first manuscript (n = 46) demonstrated moderate levels of feasibility and strong preliminary efficacy of the BEAM program, with significant reductions in maternal depression, anxiety, parenting stress, and child internalizing symptoms. The second manuscript (n = 116) found that there was a high proportion of individuals who reported notable relationship distress (60%). Better overall partner support and satisfaction were associated with less mental health concerns. Moderation analyses revealed that BEAM contributed to greater reductions in overreactive discipline for mothers with lower levels of partner support or relationship satisfaction at baseline and that BEAM contributed to greater reductions in anxiety and anger at 6-month follow-up for mothers with lower levels of partner information support at baseline. Conclusion: The BEAM program shows promise as an accessible and scalable digital intervention for mothers. Many individuals report relationship dissatisfaction, and those with lower satisfaction and support appeared to benefit more from BEAM. Findings will help direct the program to the most suitable populations. Implementing relationship enhancement strategies may be a future direction to address this population's high levels of relationship dissatisfaction.

description: While planning a new bridge construction the risk of traffic accidents due to critical wind conditions should be carefully  considered.  The  determination  of  aerodynamic  forces  and  moments  on  vehicles  is  indispensable  for  stability investigations. However, the aerodynamic coefficients of vehicle-bridge systems depend on many factors which  make  it  difficult  to  generalise  the  procedure.  This  paper  is  focusing  on  analysing  a  particular  bridge  geometry  whereby  aerodynamic  coefficients  were  predicted  by  means  of  CFD.  The  accuracy  of  the  numerical  model  was  validated  with  the  aid  of  experimental  data  from  wind  tunnel  tests.  Specifically,  this  work  was  conducted to investigate the effect of the wind barrier considering various wind flow angles and vehicle speeds. Mean forces and moments on the vehicle were analysed depending on both absolute and relative wind flows. The impact  of  performing  relative  motion  between  vehicle  and  bridge  deck  was  investigated.  Simulation  results  without wind barrier are qualitatively in good agreement with results found in literature. Nevertheless, the flow situation with  wind  barrier  and  relative  motion  is  significantly  more complex. Thus,  CFD  modelling  has  dominating advantages over wind tunnel tests in terms of both parameter variation and model accuracy. In this particular  case  CFD  modelling  is indeed essential in  order  to  represent  all  possible  wind  flow  angles  and  the  relative  motion  between  the  vehicle  and  the  bridge  deck  which  remains  difficult  or  rather  hardly  possible  to  perform in the wind tunnel.

description: This bilingual volume of essays, Kazan, Moscow, St. Petersburg: Multiple Faces of the Russian Empire (1997) represents one of the first efforts to create a conversation among historians in the former Soviet Union, the United States, and Europe. Based on a conference held in Kazan, Tatarstan, in the summer of 1994, the book addresses the theme of empire, broadly conceived, and includes participants from the cities mentioned in the title, as well as scholars from the U.S. and Italy. The intention was, in part, to reflect different approaches and begin to bring them into dialogue. Several of the articles have been influential in shaping the prevalent discussion of the Russian empire in the intervening twenty years.

description: We investigate spin and optical properties of individual nitrogen-vacancy centers located within 1-10 nm from the diamond surface. We observe stable defects with a characteristic optically detected magnetic resonance spectrum down to lowest depth. We also find a small, but systematic spectral broadening for defects shallower than about 2 nm. This broadening is consistent with the presence of a surface paramagnetic impurity layer [Tisler et al., ACS Nano 3, 1959 (2009)] largely decoupled by motional averaging. The observation of stable and well-behaved defects very close to the surface is critical for single-spin sensors and devices requiring nanometer proximity to the target.

description: In this paper, which is part of a study of positive representations of locally compact groups in Banach lattices, we initiate the theory of positive representations of finite groups in Riesz spaces. If such a representation has only the zero subspace and possibly the space itself as invariant principal bands, then the space is Archimedean and finite dimensional. Various notions of irreducibility of a positive representation are introduced and, for a finite group acting positively in a space with sufficiently many projections, these are shown to be equal. We describe the finite dimensional positive Archimedean representations of a finite group and establish that, up to order equivalence, these are order direct sums, with unique multiplicities, of the order indecomposable positive representations naturally associated with transitive $G$-spaces. Character theory is shown to break down for positive representations. Induction and systems of imprimitivity are introduced in an ordered context, where the multiplicity formulation of Frobenius reciprocity turns out not to hold.

description: In Mobile Cloud Computing (MCC), Virtual Machine (VM) migration based process offloading is a dominant approach to enhance Smart Mobile Devices (SMDs). A challenging aspect of VM deployment is the additional computing resources usage in the deployment and management of VM which obliges computing resources for VM creation and configuration. The management of VM comprises computing resources exploitation in the monitoring of VM in entire lifecycle and physical resources management for VM on SMDs. Therefore, VM migration based application offloading requires additional computing resource. Consequently computing resources demand and execution time of the application increases respectively. In this paper, we empirically review the impact of VM deployment and management on the execution time of application in diverse scenarios. We investigate VM deployment and management for application processing in simulation environment by employing CloudSim: a simulation toolkit that provides an extensible simulation framework to model VM deployment and management for application processing in cloud infrastructure. The significance of this work is to ensure that VM deployment and management necessitates additional computing resources on SMD for application offloading. We evaluate VM deployment and management in application processing by analyzing Key Performance Parameters (KPPs) in different scenarios; such as VM deployment, the execution time of applications, and total execution time of the simulation. We use KPPs to assess deviations in the results of diverse experimental scenarios. The empirical analysis concludes that VM deployment and management oblige additional resources on computing host which make it a heavyweight approach for process offloading on smart mobile device.
