Development and application of in-cylinder fuel concentration and pyrometry optical diagnostic tools in diesel-ignited dual-fuel natural gas engines
Creators: name: Yeo, Jeff
Publisher: name: University of British Columbia
Year: 2017

description: In recent years, government policies have mandated significant reductions in emissions of greenhouse gases (GHG) and particulate matter (PM) from heavy-duty, on-highway transportation applications. This has necessitated the development of clean engine technologies such as dual-fuel combustion of natural gas (NG) in compression ignition (CI) engines. With these new engine developments, the need to understand and optimize these technologies to meet emission regulations becomes crucial. Traditional engine research relies on thermodynamic methods and exhaust analysis to examine performance and emission trends present across real-world operating conditions – more recently, optical tools have become increasingly accessible and are providing new methods of understanding combustion phenomena. Interpretation however, is often not directly translatable between optical and thermodynamic engines due to the many mechanical differences between the two. This work aims to provide the foundations for a new “thermo-optical” approach which combines conventional thermodynamic analysis with optical insight into combustion phenomenon to bridge the gap between thermodynamic and optical engine studies. The development and application of an optical probe performing line of sight pyrometry for in-cylinder soot concentration and temperature measurements, as well as the implementation of a probe for in-cylinder local fuel concentration measurements is detailed. The probes are operated in a 2-litre single-cylinder research engine capable of thermodynamic (“all-metal”) and optical configurations and were utilized under two vastly different operating strategies. These strategies used premixed methane with a diesel pilot (DIDF), and High Pressure Direct Injection (HPDI) for non-premixed NG with a diesel pilot. The pyrometry probe demonstrated the effect of HPDI injection parameters on in-cylinder PM concentration while fuel concentration measurements were used to identify the combustion mode under DIDF conditions, and to provide insight to HPDI injection and combustion characteristics. The probes’ performance and capabilities were evaluated under thermodynamic and optical configurations, with high-speed cameras complementing the probes during optical operation. The framework for interpretation in the “thermo-optical” methodology was developed through analysis of the local fuel concentration, soot concentration and temperature, spatially resolved optical results, and conventional apparent heat release rate (AHRR) analysis.

description: We consider G-equivariant dimensional reduction of Yang-Mills theory with torsion on manifolds of the form MxG/H where M is a smooth manifold, and G/H is a compact six-dimensional homogeneous space provided with a never integrable almost complex structure and a family of SU(3)-structures which includes a nearly Kahler structure. We establish an equivalence between G-equivariant pseudo-holomorphic vector bundles on MxG/H and new quiver bundles on M associated to the double of a quiver Q, determined by the SU(3)-structure, with relations ensuring the absence of oriented cycles in Q. When M=R^2, we describe an equivalence between G-invariant solutions of Spin(7)-instanton equations on MxG/H and solutions of new quiver vortex equations on M. It is shown that generic invariant Spin(7)-instanton configurations correspond to quivers Q that contain non-trivial oriented cycles.

description: One of the goals of this article is to define a an unified setting adapted to the description of means (normalized integrals or invariant means) on an infinite product of measured spaces with infinite measure. We first remark that some known examples coming from the theory of metric measured spaces and also from oscillatory integrals are obtained as limits of means with respect to finite measures. Then, we explore in a systematic way the limit of means of the type $$ \lim \frac{1}{μ(U_n)} \int_{U_n} f dμ$$ where $μ$ is a a $σ-$finite Radon measure $μ.$ In some cases, we get a linear extension of the limit at infinity. Then, the mean value on an infinite product is defined, first for cylindrical functions and secondly taking the uniform limit. Finally, the mean value for the heuristic Lebesgue measure on a separable infinite dimensional topological vector space (but principally on a Hilbert space) is defined. This last object is shown to be invariant by translation, scaling and restriction.

description: We construct solutions to Burgers type equations perturbed by a multiplicative space-time white noise in one space dimension. Due to the roughness of the driving noise, solutions are not regular enough to be amenable to classical methods. We use the theory of controlled rough paths to give a meaning to the spatial integrals involved in the definition of a weak solution. Subject to the choice of the correct reference rough path, we prove unique solvability for the equation and we show that our solutions are stable under smooth approximations of the driving noise.

description: In this work, we construct and study certain classes of infinite dimensional Lie groups that are modelled on weighted function spaces. In particular, we construct a Lie group of weighted diffeomorphisms on a Banach space. Further, we also construct certain types of weighted mapping groups. Both the weighted diffeomorphism groups and the weighted mapping groups are shown to be regular Lie groups in Milnor's sense. We also discuss semidirect products of the former groups. Moreover, we study the integrability of Lie algebras of certain vector fields.

description: We continue the study of n-point correlation functions of half-BPS protected operators in N=4 super-Yang-Mills theory, in the limit where the positions of the adjacent operators become light-like separated. We compute the l-loop corrections by making l Lagrangian insertions. We argue that there exists a simple relation between the (n+l)-point tree-level correlator with l Lagrangian insertions and the integrand of the n-particle l-loop MHV scattering amplitude, as obtained by the recent momentum twistor construction of Arkani-Hamed et al. We present several examples of this new duality, at one and two loops.

description: A new test is proposed for the weak white noise null hypothesis. The test is based on a new automatic choice of the order for a Box-Pierce or Hong test statistic. The test uses Lobato (2001) or Kuan and Lee (2006) HAC critical values. The data-driven order choice is tailored to detect a new class of alternatives with autocorrelation coefficients which can be $o(n^{-1/2})$ provided there are enough of them. A simulation experiment illustrates the good behavior of the test both under the weak white noise null and the alternative.

description: The Orlov spectrum is a new invariant of a triangulated category. It was introduced by D. Orlov building on work of A. Bondal-M. van den Bergh and R. Rouquier. The supremum of the Orlov spectrum of a triangulated category is called the ultimate dimension. In this work, we study Orlov spectra of triangulated categories arising in mirror symmetry. We introduce the notion of gaps and outline their geometric significance. We provide the first large class of examples where the ultimate dimension is finite: categories of singularities associated to isolated hypersurface singularities. Similarly, given any nonzero object in the bounded derived category of coherent sheaves on a smooth Calabi-Yau hypersurface, we produce a new generator by closing the object under a certain monodromy action and uniformly bound this new generator's generation time. In addition, we provide new upper bounds on the generation times of exceptional collections and connect generation time to braid group actions to provide a lower bound on the ultimate dimension of the derived Fukaya category of a symplectic surface of genus greater than one.

A parameterized Douglas-Rachford algorithm : theory and applications
Creators: name: Wang, Dongying
Publisher: name: University of British Columbia
Year: 2017

description: Douglas-Rachford algorithm is important due to its applications on the Heron problem and on the image denoising. Mathematically, it can be considered as finding a point such that the point belongs to a zero set of the sum of two maximally monotone operators. In this thesis, previous work on Douglas-Rachford algorithm is presented and the Douglas-Rachford algorithm with a changed parameter is considered. I give it the name "α-Douglas-Rachford algorithm". The new algorithm which has the changed parameter is shown to have a convergent result and other conclusions similar to those of the classic Douglas-Rachford algorithm. At the same time, it has been shown that the application of the α-Douglas-Rachford algorithm is wider than the application of the classic one. Later on, the α-Douglas-Rachford algorithm is proved to converge to the solution of the composited monotone inclusion problems, and in a special-limit case, it has some other properties. The numerical experiments confirm that the α-Douglas-Rachford algorithm does have the properties that I proved theoretically.

Three-body (Kbar-N-pi)--(pi-Y-pi) coupled channel Faddeev equations with relativistic kinematics are solved in search for quasibound poles in the complex plane, leading to a I(JP)=1(3/2-) (Kbar-N-pi) quasibound state at M ~ (1570 +/- 10) MeV and width greater than 60 MeV near the (Kbar-N-pi) threshold.

description: Specific heat measurements in zero magnetic field are presented on a homologous series of geometrically frustrated, antiferromagnetic, Heisenberg garnet systems. Measurements of Gd3Ga5O12, grown with isotopically pure Gd, agree well with previous results on samples with naturally abundant Gd, showing no ordering features. In contrast, samples of Gd3Te2Li3O12 and Gd3Al5O12 are found to exhibit clear ordering transitions at 243 mK and 175 mK respectively. The effects of low level disorder are studied through dilution of Gd3+ with non-magnetic Y3+ in Gd3Te2Li3O12. A thorough structural characterization, using X-ray diffraction, is performed on all of the samples studied. We discuss possible explanations for such diverse behavior in very similar systems.

The Cognitive-Affective-Motivation Model of Learning (CAMML): Standing on the Shoulders of Giants
Creators: McGrew, Kevin S.
Publisher: name: University of Alberta Library
Year: 2022

The Cognitive-Affective-Motivation Model of Learning (CAMML) is a proposed framework for integrating contemporary motivation, affective (Big 5 personality) and cognitive (CHC theory) constructs in the practice of school psychologists (SPs). The central tenet of this article is that SPs should integrate motivation alongside affective and cognitive constructs vis-à-vis an updated trilogy-of-the-mind (cognitive, conative, affective) model of intellectual functioning. CAMML builds on Richard Snow’s seminal research on academic aptitudes—which are not synonymous with cognitive abilities.  Learning aptitude complexes are academic domain-specific cognitive abilities and personal investment mechanisms (motivation and self-regulation) that in concert produce a student’s readiness to learn in a specific domain.  CAMML incorporates the “crossing the Rubicon” commitment pathway model of motivated self-regulated learning.  It is recommended SPs take a fresh look at motivation theory, constructs, and research, embedded in the CAMML aptitude framework, by going back-to-the-future guided by the wisdom of giants from the field of cognition, intelligence, and educational psychology.
An ER-based Framework for Declarative Web Programming

description: We describe a framework to support the implementation of web-based systems intended to manipulate data stored in relational databases. Since the conceptual model of a relational database is often specified as an entity-relationship (ER) model, we propose to use the ER model to generate a complete implementation in the declarative programming language Curry. This implementation contains operations to create and manipulate entities of the data model, supports authentication, authorization, session handling, and the composition of individual operations to user processes. Furthermore, the implementation ensures the consistency of the database w.r.t. the data dependencies specified in the ER model, i.e., updates initiated by the user cannot lead to an inconsistent state of the database. In order to generate a high-level declarative implementation that can be easily adapted to individual customer requirements, the framework exploits previous works on declarative database programming and web user interface construction in Curry.

description: Earth-mass dark matter microhalos with size of ~100 AUs are the first structures formed in the universe, if the dark matter of the Universe are made of neutralino. Here, we report the results of ultra-high-resolution simulations of the formation and evolution of these microhalos. We found that microhalos have the central density cusps of the form $ρ\propto r^{-1.5}$, much steeper than the cusps of larger dark halos. The central regions of these microhalos survive the encounters with stars except in very inner region of the galaxy down to the radius of a few hundreds pcs from the galactic center. The annihilation signals from nearest microhalos are observed as gamma-ray point-sources (radius less than 1'), with unusually large proper motions of ~0.2 degree per year. Their surface brightnesses are ~10% of that of the galactic center. Their S/N ratios might be better if they are far from the galactic plane. Luminosities of subhalos are determined only by their mass, and they are more than one order of magnitude luminous than the estimation by Springel et al. (2008): A boost factor can be larger than 1000. Perturbations to the millisecond pulsars by gravitational attractions of nearby earth-mass microhalos can be detected by the observations of Parkes Pulsar Timing Array (PPTA).

An investigation into the genetic basis of variation in hypoxia tolerance in Atlantic salmon
Creators: name: Lin, Xiang
Publisher: name: University of British Columbia
Year: 2017

description: Episodes of hypoxia are becoming more common along the British Columbia (BC) coast especially in the late summer. When dissolved oxygen drops below optimum levels, fish survival, growth and reproduction are affected; moreover, hypoxia can be lethal to fish, resulting in economic losses to salmon farmers. As a first step towards addressing this challenge for BC salmon farmers, the objectives of this study were to characterize variation in hypoxia tolerance in Atlantic salmon (Salmo salar) under culture conditions and identify the genetic basis of this variation in the strains of salmon used by the aquaculture producer Marine Harvest Canada. Using time-to-loss-of-equilibrium (LOE) following exposure to acute hypoxia (2.1 mg/L) as an index of hypoxia tolerance, I show that there are significant differences in hypoxia tolerance within and between the strains of Atlantic salmon examined. For adults in seawater, time-to-LOE at 2.1 mg/L DO ranged from 4.6 min to 126.9 min, and the McConnell strain had better hypoxia tolerance than the Mowi strain. A similar pattern was observed for smolts in freshwater, with time-to-LOE ranging from 4.5 min before 2.1 mg/L DO was reached to 355.4 min at 2.1 mg/L DO. Genotyping-by-sequencing (GBS) was used to identify single-nucleotide polymorphism (SNP) markers in these strains for use in a genome-wide association study (GWAS). GWAS in adult fish in seawater revealed two SNPs associated with hypoxia tolerance using genome-wide FDR correction, and six SNPs associated with hypoxia tolerance using chromosome-wide FDR correction. In contrast, GWAS in smolts in freshwater identified one SNP using genome-wide FDR correction and one SNP using chromosome-wide FDR correction. There was no overlap in the SNPs identified as associated with hypoxia tolerance at these two life stages. In addition, I identified four significant SNPs associated with body mass in adults with chromosome-wide FDR correction and two SNPs associated with body mass with genome-wide FDR correction and fifty-eight SNPs associated with body mass with chromosome-wide FDR correction. These findings provide promise for follow-up work on SNP markers that could potentially be used for marker-assisted selection to improve hypoxia tolerance and growth in Atlantic salmon.

It is shown that an infrared fixed point appears in the broken symmetric phase of the models, which induces a dynamical scale, that can be identified with the correlation length. This enables one to identify the type of the phase transition which shows similarity to the one appearing in the crossover scale. The critical exponent $ν$ of the correlation length also proved to be equal in the crossover and the infrared scaling regimes.

description: In many Indigenous communities, the wellbeing of waterways correlates to the health of the population that it supports. However, current laws and water governance systems often fail to protect water sources and jeopardizes health and wellbeing, particularly in Indigenous communities. This study, curated by an Anishinaabe First Nations community located in Ontario on the Lake of the Woods (LOTW), was designed to detail the varying impacts of adverse water quality on people in the community. A community-based participatory research approach included interviews with Elders and key informants to understand lived experiences of adverse water quality, sources of pollution, and individual and community impacts. Key findings revealed changes in water quality within and between years, with water quality degrading over time. Further, changes in water quality were associated with changes in the community’s health, food sources, and activities. Finally, a paternalistic colonial history between Indigenous people and the Government of Canada continues to resonate and cause strained jurisdictional relations between the two groups. Opportunities and future water stewardship strategies require the active participation and inclusion of Indigenous people in policymaking, programming, and water management. As proposed by the LOTW community, this includes improving water quality monitoring, upgrading septic systems in the community, reintroducing wild rice to the shorelines, and creating water activities programming for Indigenous youth.

description: An identifying code is a subset of vertices of a graph such that each vertex is uniquely determined by its neighbourhood within the identifying code. If $\M(G)$ denotes the minimum size of an identifying code of a graph $G$, it was conjectured by F. Foucaud, R. Klasing, A. Kosowski and A. Raspaud that there exists a constant $c$ such that if a connected graph $G$ with $n$ vertices and maximum degree $d$ admits an identifying code, then $\M(G)\leq n-\tfrac{n}{d}+c$. We use probabilistic tools to show that for any $d\geq 3$, $\M(G)\leq n-\tfrac{n}{Θ(d)}$ holds for a large class of graphs containing, among others, all regular graphs and all graphs of bounded clique number. This settles the conjecture (up to constants) for these classes of graphs. In the general case, we prove $\M(G)\leq n-\tfrac{n}{Θ(d^{3})}$. In a second part, we prove that in any graph $G$ of minimum degree $δ$ and girth at least 5, $\M(G)\leq(1+o_δ(1))\tfrac{3\logδ}{2δ}n$. Using the former result, we give sharp estimates for the size of the minimum identifying code of random $d$-regular graphs, which is about $\tfrac{\log d}{d}n$.

description: The North and South Saskatchewan River sub-basins comprise the Saskatchewan River Basin (SRB), which originates in the eastern slopes of the Rocky Mountains of Alberta (Canada) and Montana (USA), extending across the vast landscape of three Canadian Provinces. The SRB is the most populated region of the Northern Great Plains, where water demands from agriculture, industry, and municipalities can be a substantial proportion of supply during periods of low flow and hydrological drought. Changing climatic conditions and shifts between periods of extreme wet and dry weather emphasize the need for a better understanding of past and future seasonal variability of the surface water balance within and between the sub-basins. Climate extremes, such as hydrological drought and excessive moisture conditions occurring simultaneously can create detrimental effects. Using a multi-species network of over 80 tree-ring chronologies, warm (May through August) and cool (December through April) season streamflow (1400–2018) were independently reconstructed for the North and South Saskatchewan River sub-basins. Departures from seasonal flow and spectral and wavelet analyses of the reconstructions indicate significant variability at inter-annual and multi-decadal scales.
Mother feels best : mobilizing negative maternal affect as postfeminist critique in contemporary horror cinema
Creators: name: Greer, Amanda
Publisher: name: University of British Columbia
Year: 2017

description: A small child is getting ready for school. His mother dresses him, pulling his jacket over his shoulders. He tries to hug her, emitting a satisfied sigh; she pushes him away. “Don’t do that!” she cries. This sequence occurs at the beginning of Jennifer Kent’s horror film, The Babadook (2014), a film that perfectly embodies contemporary horror’s capacity to critique postfeminist mothering through its use of affect and the Final Mom figure. Although the horror genre’s conventional representations of motherhood portray the institution as monstrous and abject, as in Carrie (1976) and The Brood (1979), a recent spate of horror films has demonstrated a more nuanced approach to mothering. Drawing from Carol Clover’s seminal Final Girl figure, this thesis locates a powerful and critically productive figure in these films: the Final Mom. This figure, though dissatisfied with mothering and domestic life, must defend her family against a threatening force, often with no help from others. These figures exist in a postfeminist world where New Momist parenting is expected and celebrated. This form of parenting demands that all mothers fulfill a contradiction: give yourself over completely to mothering (sacrificing one’s individual identity), while remaining sexually attractive and achieving success at work. This thesis explores how the horror genre’s new Final Mom figure critiques postfeminist mothering’s impossible expectations through mobilizing negative maternal affects. Employing a tripartite model of affect theory, in which affect is seen to travel between narratives, character bodies, and film form itself, this thesis argues that Final Mom horror films use negative maternal affects to critique and denaturalize postfeminist mothering structures. Irritation occupies a critical role in The Babadook, while envy will be discussed in relation to We Need to Talk About Kevin (2011). These under-discussed, unpleasant affects will provide in-depth cultural critiques of contemporary mothering’s unfulfillable expectations, proving their politically productive potentials. What’s more, unpleasant affects like irritation and envy are emphasized as natural components of mothering, rather than shameful. This thesis exposes the Final Mom’s potential to celebrate mothering’s “bad” feelings, to accept these affects as natural to all mothering experiences.

description: One of the greatest discoveries of modern times is that of the expanding Universe, almost invariably attributed to Hubble (1929). What is not widely known is that the original treatise by Lemaitre (1927) contained a rich fusion of both theory and of observation. Stiglers law of eponymy is yet again affirmed: no scientific discovery is named after its original discoverer (Merton, 1957). An appeal is made for a Lemaitre Telescope, to honour the discoverer of the expanding universe.

description: Thermal leptogenesis explains the observed matter-antimatter asymmetry of the universe in terms of neutrino masses, consistent with neutrino oscillation experiments. We present a full quantum mechanical calculation of the generated lepton asymmetry based on Kadanoff-Baym equations. Origin of the asymmetry is the departure from equilibrium of the statistical propagator of the heavy Majorana neutrino, together with CP violating couplings. The lepton asymmetry is calculated directly in terms of Green's functions without referring to "number densities". Compared to Boltzmann and quantum Boltzmann equations, the crucial difference are memory effects, rapid oscillations much faster than the heavy neutrino equilibration time. These oscillations strongly suppress the generated lepton asymmetry, unless the standard model gauge interactions, which cause thermal damping, are properly taken into account. We find that these damping effects essentially compensate the enhancement due to quantum statistical factors, so that finally the conventional Boltzmann equations again provide rather accurate predictions for the lepton asymmetry.

Agricultural productivity and climate smart solutions in southwestern Bangladesh

description: This study evaluated the impacts of fertilizer deep placement (FDP) technology introduced by the International Fertilizer Development Center (IFDC) in the designated Feed the Future (FTF) districts in Southwestern Bangladesh. The traditional method of applying fertilizer to rice in this area is broadcasting urea on the flooded rice fields just before planting the crop and then broadcasting more urea after the rice is established.  The rice plants absorb only about 30% of the nitrogen that is broadcasted and the rest ends up polluting water sources with excess nitrates and emitting nitrous oxide (N20) through volatilization. The IFDC introduced fertilizer deep placement (FDP) technology to farmers in Bangladesh to improve domestic food security and farmer resiliency among the most vulnerable populations to climate change.  According to the IFDC, FDP increases the efficiency of nitrogen applied by placing urea briquettes 7-10 cm into the soil by the roots. The urea briquettes slowly release nitrogen in the soil increasing the plant’s absorption of nutrients and decreases nitrates released into the air, irrigated water and runoff. The objective of this research was to examine the effects of adopting FDP technology on farmer yields, fertilizer productivity and revenues and the differences in fertilizer input (kg/ha) between broadcasting and FDP application. This study uses data from a survey of 2,000 farmers from 10 districts in Southwest Bangladesh collected in 2015 and 2016. All farmers surveyed used either deep-placement and/or broadcast prilled urea, thus all farmers used fertilizer during production. The surveyed population is divided into two treatment groups: (1) Fully adopted FDP; and (2) Mixed users using both fertilizer practices. Their yields, revenues, fertilizer productivity and average fertilizer inputs are analyzed through OLS fixed effects regressions. The results show a positive significant relationship between fertilizer deep placement use and yields, total revenues, net-revenues and fertilizer productivity. There is a negative significant relationship between FDP technology and average fertilizer input. The farmers that fully adopted fertilizer deep placement had higher yields, revenues and fertilizer productivity, and less fertilizer input than the mixed and broadcasted users. Additionally, the adoption behavior in the 2015 treatment groups is compared to the behavior in 2016 from the surveyed households. Our study shows that deep-placement technology can be a climate-smart practice in helping farmers mitigate greenhouse gas emissions  and slow climate change; however, it continues to face adoption barriers for farmers in Bangladesh.
Lollipop diagrams in defect N=4 super Yang-Mills theory

description: In this thesis, we have studied the lollipop diagrams in defect $\mathcal{N}$=4 super Yang-Mills field theory with nontrivial background, which is dual to the D3-D5 brane system with the probe D5 brane carrying k units of flux. Using the framework for performing loop computations for this system built by Buhl-Mortensen, Leeuw, Ipsen, Kristjansen and Wilhelm, we prove that for arbitrary N and k, the contribution of the lollipop diagrams to the one-point function is zero. This improves their result, where they take the planar limit N>>1 and the probe brane limit k/N<<1.

description: The discovery of supersymmetry (SUSY) via action of the cold dark matter candidate is being led on the indirect collider production front by the LHC, and correspondingly by the XENON100 collaboration on the direct detection front. We undertake a dual case study of the specific SUSY signatures which the No-Scale flipped SU(5) x U(1)_X grand unified theory with TeV-scale vector-like particles (No-Scale F-SU(5)) would exhibit at each of these experiments. We demonstrate a correlation between the near-term prospects of these two distinct approaches. We feature a dark matter candidate which is over 99% bino due to a comparatively large Higgs bilinear mass μ-term around the electroweak scale, and thus automatically satisfy the current constraints from the XENON100 and CDMS/EDELWEISS experiments. We do however expect that the ongoing extension of the XENON100 run may effectively probe our model. Likewise, our model is also currently being probed by the LHC via a search for events with ultra-high multiplicity hadronic jets, which are a characteristic feature of the distinctive No-Scale F-SU(5) mass hierarchy.

description: We propose a simple distributed algorithm for balancing indivisible tokens on graphs. The algorithm is completely deterministic, though it tries to imitate (and enhance) a random algorithm by keeping the accumulated rounding errors as small as possible. Our new algorithm surprisingly closely approximates the idealized process (where the tokens are divisible) on important network topologies. On d-dimensional torus graphs with n nodes it deviates from the idealized process only by an additive constant. In contrast to that, the randomized rounding approach of Friedrich and Sauerwald (2009) can deviate up to Omega(polylog(n)) and the deterministic algorithm of Rabani, Sinclair and Wanka (1998) has a deviation of Omega(n^{1/d}). This makes our quasirandom algorithm the first known algorithm for this setting which is optimal both in time and achieved smoothness. We further show that also on the hypercube our algorithm has a smaller deviation from the idealized process than the previous algorithms.
