description: This study investigated the attitudes of students to practical agriculture and examined whether there were significant differences in the mean scores in Practical Agriculture Achievement Test (PAAT) among the three categories of schools used for this study. This study was a descriptive survey design carried out in Ibadan Metropolis, Oyo State, Nigeria. Nine (9) public secondary schools were randomly selected from three different Local Government Areas (LGAs) out of eleven (11) present in Ibadan zone comprising three (3) Boys' only, three (3) Girls' only and three (3) Coeducational schools. A total of two hundred and fifty-five (255) Senior Secondary Schools (SSSIII) students from three selected categories of schools participated in this study. PAAT and AtPAQ were the research instruments used for data collection. The data collected were analysed using descriptive statistics, Chi-square test of independence, ANOVA and multiple comparison techniques. The ANOVA test was significant (p = .00). Boys' only schools had the highest mean scores of 48.14 followed by Girls' only schools with 42.72 while Coeducational schools had 34.92. Least Significant Difference (LSD), a multiple comparison technique, on the ANOVA showed that there existed significant differences in the mean scores of PAAT for all pairs of the three categories of schools. There was no association between students' mean scores and selected attitudinal variables. The study recommended awareness campaign on the importance of agricultural science education and training as a vocational subject which can make them self-employed after leaving school and also boost agricultural productivity in the nation.

description: In this paper, we study the Online Network Formation Problem (ONFP) for a mobile multi-robot system. Consider a group of robots with a bounded communication range operating in a large open area. One of the robots has a piece of information which has to be propagated to all other robots. What strategy should the robots pursue to disseminate the information to the rest of the robots as quickly as possible? The initial locations of the robots are unknown to each other, therefore the problem must be solved in an online fashion. For this problem, we present an algorithm whose competitive ratio is $O(H \cdot \max\{M,\sqrt{M H}\})$ for arbitrary robot deployments, where $M$ is the largest edge length in the Euclidean minimum spanning tree on the initial robot configuration and $H$ is the height of the tree. We also study the case when the robot initial positions are chosen uniformly at random and improve the ratio to $O(M)$. Finally, we present simulation results to validate the performance in larger scales and demonstrate our algorithm using three robots in a field experiment.

description: Over the past decades the area of medical imaging has evolved rapidly. This is demonstrated by the increasing number of imaging systems in hospitals and research facilities and the increasing number of people specializing in the field. New technologies have emerged to support ionizing radiation imaging techniques, based on one simple goal, which is making people life healthier and easier. Most of diagnostic protocols include the use of ionizing radiation, as the main source of signal production and detection. These techniques aim to be fast and minimally invasive, while providing lot of information about the health status of the subject, in terms of diagnostic characteristics. In this project, the most common and popular imaging techniques will be discussed, which have been reviewed and analyzed. Namely, this study discusses the several X-ray procedures, such as the X-ray imaging and Computed Tomography. PET and SPECT are also part of this study and are presented in detail. In the last part of this thesis, the results by a series of experiments are presented, executed to highlight their applicability, strong and weak points, as well as a wide range of applications that have been performed in a pre-clinical lab.

description: Let $V$ be a complete discrete valuation ring with fraction field $F$ of characteristic zero and with residue field $\mathbb{F}$. We introduce analytic cyclic homology of complete torsion-free bornological algebras over $V$. We prove that it is homotopy invariant, stable, invariant under certain nilpotent extensions, and satisfies excision. We use these properties to compute it for tensor products with dagger completions of Leavitt path algebras. If $R$ is a smooth commutative $V$-algebra of relative dimension $1$, then we identify its analytic cyclic homology with Berthelot's rigid cohomology of $R\otimes_{V}\mathbb{F}$.

description: An oscillating universe cycles through a series of expansions and contractions. We propose a model in which ``phantom'' energy with $p < -ρ$ grows rapidly and dominates the late-time expanding phase. The universe's energy density is so large that the effects of quantum gravity are important at both the beginning and the end of each expansion (or contraction). The bounce can be caused by high energy modifications to the Friedmann equation, which make the cosmology nonsingular. The classic black hole overproduction of oscillating universes is resolved due to their destruction by the phantom energy.

description: The 2-- to 1--dimensional crossover of the localisation length of electrons confined to a disordered quantum wire of finite width $L_y$ is studied in a model of electrons moving in the potential of uncorrelated impurities. An analytical formula for the localisation length is derived, describing the dimensional crossover as function of width $L_y$, conductance $g$ and perpendicular magnetic field $B$ . On the basis of these results, the scaling analysis of the quantum Hall effect in high Landau levels, and the delocalisation transition in a quantum Hall wire are reconsidered.

Scalable rendering of data visualisations using web frameworks
Creators: name: Fernando, Theverathanthreege Senaka Leo
Publisher: name: Imperial College London
Year: 2020

description: Big data has not only created new opportunities for industrial and academic research, but also introduced many challenging problems. Collaborative decision making is one of several mechanisms for addressing these challenges. Scalable resolution display environments (SRDEs) have become increasingly popular in the past two decades as a utility for supporting collaborative decision making. Despite this popularity, the concept of a data observatory built using several SRDEs is relatively new. The Data Science Institute of Imperial College London is one of the first institutions to facilitate such an environment. SRDEs require specialised middleware to operate them and only a few dozen variants have been developed so far. It does not come as a surprise that none of these middleware were suitable for the requirements of operating the four distinctive SRDEs found at the institute. This thesis proposes and validates a novel strategy for scalable rendering of data visualisations using web frameworks. It explores the domain of scalable rendering, introduces various types of SRDEs and thereafter evaluates a number of existing middleware presenting their capabilities and limitations, establishing the key requirements of a middleware for scalable rendering of data visualisations. It proposes that such a middleware needs a combination of a non-invasive application programming model, a modular multi-tier architecture to enable multiple parallel rendering strategies and data distribution through synchronised execution, and a web-based ecosystem for developing composite data visualisations. This hypothesis is validated using a quantitative approach by means of extensive performance and scalability tests and studies on user expectations and usage patterns, and thereafter using a qualitative approach taking three real world projects as case studies. The study is based on two open source middleware frameworks, Tuoris and OVE, which were developed to operate the SRDEs at the institute.

description: The phase-field method is reviewed from the general perspective of converting a free boundary problem into a set of coupled partial differential equations. Its main advantage is that it avoids front tracking by using phase fields to locate the fronts. These fields interpolate between different constant values in each bulk phase through diffuse interfaces of finite thickness. In solidification, the phase fields can be understood as order parameters, and the model is often derived to dynamically minimise a free energy functional. However, this is not a necessary requirement, and both derivations involving a free energy (basic solidification model) and not (first viscous fingering model) are worked out. In any case, the model is required to reproduce the original free boundary problem in the limit of vanishing interface thickness. This limit and its higher order corrections, important to make quantitative contact between simulations and experiments, are discussed for both examples. Applications to fluctuations in solidification, the growth of liquid crystal mesophases, and viscous fingering in Hele-Shaw cells are presented.

description: In this work, we present a new, high performance algorithm for background rejection in imaging atmospheric Cherenkov telescopes. We build on the already popular machine-learning techniques used in gamma-ray astronomy by the application of the latest techniques in machine learning, namely recurrent and convolutional neural networks, to the background rejection problem. Use of these machine-learning techniques addresses some of the key challenges encountered in the currently implemented algorithms and helps to significantly increase the background rejection performance at all energies. We apply these machine learning techniques to the H.E.S.S. telescope array, first testing their performance on simulated data and then applying the analysis to two well known gamma-ray sources. With real observational data we find significantly improved performance over the current standard methods, with a 20-25\% reduction in the background rate when applying the recurrent neural network analysis. Importantly, we also find that the convolutional neural network results are strongly dependent on the sky brightness in the source region which has important implications for the future implementation of this method in Cherenkov telescope analysis.

description: Two networks are said to be linearly conjugate if the solution of their dynamic equations can be transformed into each other by a positive linear transformation. The study on dynamical equivalence in chemical kinetic systems was initiated by Craciun and Pantea in 2008 and eventually led to the Johnston-Siegel Criterion for linear conjugacy (JSC). Several studies have applied Mixed Integer Linear Programming (MILP) approach to generate linear conjugates of MAK (mass action kinetic) systems, Bio-CRNs (which is a subset of hill-type kinetic systems when the network is restricted to digraphs), and PL-RDK (complex factorizable power law kinetic) systems. In this study, we present a general computational solution to construct linear conjugates of any "rate constant-interaction function decomposable" (RID) chemical kinetic systems, wherein each of its rate function is the product of a rate constant and an interaction function. We generate an extension of the JSC to the complex factorizable (CF) subset of RID kinetic systems and show that any non-complex factorizable (NF) RID kinetic system can be dynamically equivalent to a CF system via transformation. We show that linear conjugacy can be generated for any RID kinetic systems by applying the JSC to any NF kinetic system that are transformed to CF kinetic system.

Strengthening human-robot symbiosis through multimodal sensing
Creators: name: Freer, Daniel
Publisher: name: Imperial College London
Year: 2020

description: As robotic technology has advanced throughout the ages, one of its primary functions has been to assist humans in completing difficult or dangerous tasks. Through the lens of outer space and healthcare, this thesis explores the possibility for a symbiotic relationship between humans and assistive robots by improving training protocols and with enhanced sensor data processing. This relationship is explored through several technologies: 1) a telerobotic simulator for training; 2) a wearable robotic sensing system for the arm; 3) motor imagery control of an assistive robot; and 4) autonomous five-fingered grasping. Within these platforms, various sensor types are used including electroencephalography (EEG), electromyography (EMG), tendon-based sensing, and computer vision (CV). At the intersection of these robotic technologies and sensors, the key results include a novel metric based on Riemannian geometry indicating new EEG mental workload features, and EMG analysis showing which preprocessing methods are most promising for feature selection. In addition, EEG motor imagery training protocols can be improved through novel data augmentation strategies which reduce the amount of needed training data per person, and an adaptive task-based protocol which could more readily transfer into the real world. Finally, CV-based robotic hand shaping was shown to be a promising way to achieve a robust grasp with a five-fingered gripper. The advancements made by studying each of these platforms and sensors provide a new link between humans and robots, which in turn creates more shared understanding between the biological and digital domains. It is only through this shared understanding that we can create a future where humans and robotic systems work together with efficiency and security.

description: We perform a stacking analysis of {\it Planck}, {\it AKARI}, Infrared Astronomical Satellite ($IRAS$), Wide-field Infrared Survey Eplorer ($WISE$), and {\it Herschel} images of the largest number of (candidate) protoclusters at $z\sim3.8$ selected from the Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP). Stacking the images of the $179$ candidate protoclusters, the combined infrared (IR) emission of the protocluster galaxies in the observed $12-850~μ$m wavelength range is successfully detected with $>5σ$ significance (at $Planck$). This is the first time that the average IR spectral energy distribution (SED) of a protocluster has been constrained at $z\sim4$. The observed IR SEDs of the protoclusters exhibit significant excess emission in the mid-IR compared to that expected from typical star-forming galaxies (SFGs). They are reproduced well using SED models of intense starburst galaxies with warm/hot dust heated by young stars, or by a population of active galactic nuclei (AGN)/SFG composites. For the pure star-forming model, a total IR (from 8 to 1000 $μ$m) luminosity of $19.3_{-4.2}^{+0.6}\times10^{13}~L_{\odot}$ and a star formation rate (SFR) of $16.3_{-7.8}^{+1.0}\times10^3~M_{\odot}$ yr$^{-1}$ are found whereas for the AGN/SFG composite model, $5.1_{-2.5}^{+2.5}\times10^{13}~L_{\odot}$ and $2.1^{+6.3}_{-1.7}\times10^3~M_{\odot}$ yr$^{-1}$ are found. Uncertainty remaining in the total SFRs; however, the IR luminosities of the most massive protoclusters are likely to continue increasing up to $z\sim4$. Meanwhile, no significant IR flux excess is observed around optically selected QSOs at similar redshifts, which confirms previous results. Our results suggest that the $z\sim4$ protoclusters trace dense, intensely star-forming environments that may also host obscured AGNs missed by the selection in the optical.

Aeroelasticity of very flexible aircraft at low altitudes
Creators: name: Del Carre De La Portilla, Alfonso
Publisher: name: Imperial College London
Year: 2020

description: This work deals with the nonlinear aeroelastic response of very flexible aircraft at low altitude. In order to study it, an efficient nonlinear aeroelasticity framework, SHARPy, has been written and validated. With it, time domain nonlinear aeroelastic simulations of a representative High Altitude, Long Endurance (HALE) very flexible aircraft immersed in 3-D low altitude boundary layer velocity fields have been conducted. Obtained loads have shown a very strong dependency with the turbulence model used in the velocity field generation. The features of the flow affecting loads the most are the span-varying character of the velocity distribution and the coherent structures that can only be captured with physics-based turbulence modelling. Another relevant, challenging to tackle numerically, part of the low altitude segment of typical HALE missions is their reliable deployment. In order to study it, a complex simulation of a catapult-assisted take off has been set up. This highly unsteady manoeuvre is characterised by large velocity and structural deflection ranges in a short period of time. This problem requires highly robust structural dynamics capabilities, as well as an accurate unsteady aerodynamics solver. A parametric study of the manoeuvre is included. Thanks to the improved efficiency of the code, the catapult take off problem can be optimised without the need for further simplifications. A novel hybrid optimisation algorithm based on Bayesian Optimisation and local gradient-less methods suitable for constrained expensive cost functions with low dimensionality is presented and applied to the launch problem. When optimising for a combination of ground clearance and wing root loads, the resulting manoeuvres show a strong dependency with the maximum ramp length constraint. This introduces a link between release velocity, acceleration and ramp length that affects the cost of the manoeuvre in a complex manner. The code used in all these simulations has been released under an Open Source license.

description: A light-front Hamiltonian reproducing the results of two-dimensional quantum electrodynamics in the Lorentz coordinates is constructed using the bosonization procedure and an analysis of the bosonic perturbation theory in all orders in the fermion mass. The resulting Hamiltonian involves a supplementary counterterm in addition to the usual terms appearing in the naive light-front quantization. This term is proportional to a linear combination of zeroth fermion modes (which are multiplied by a factor compensating the charge and fermion number). The coefficient of the counterterm has no ultraviolet divergence, depends on the value of the fermion condensate in the θ-vacuum, and is linear in this value for a small fermion mass.

description: Big data is a new driver of the world economic and societal changes. The world’s data collection is reaching a tipping point for major technological changes that can bring new ways in decision making, managing our health, cities, finance and education. While the data complexities are increasing including data’s volume, variety, velocity and veracity, the real impact hinges on our ability to uncover the `value’ in the data through Big Data Analytics technologies. Big Data Analytics poses a grand challenge on the design of highly scalable algorithms and systems to integrate the data and uncover large hidden values from datasets that are diverse, complex, and of a massive scale. In this paper, we explain the concept, characteristics & need of Big Data & different offerings available in the market to explore unstructured large data.

Scenario generation

description: The city of Basel has become a test field innovative mobility solutions in the past years. Using paid on-street parking, a free-floating car-sharing scheme (the first one in Switzerland), Uber and a potential railway line underneath the city centre, the transport network is supposed to become more efficient and, hence ready for the future. Yet, for most novel policy measures and mobility services, their respective use and impact is still unclear. To study them, disaggregated transport models such as agent-based microsimulation framework MATSim are required. While several methodologies to create MATSim scenarios already exist, only few are documented in detail. Also, Basel presents a special case, because it is located at an international border, with its agglomeration stretching into three countries (Germany, France and Switzerland). Hence, the model for the Basel region had to be generated based on a fused data set. This paper presents the data sources and methods used to set up the MATSim scenario for Basel for the year 2015. It is meant to be both a documentation for users of the scenario and a guideline for the creation of other MATSim scenarios in the context of scarce or heterogeneous data sources.

Using passively collected data to investigate social travel
Creators: name: Dubernet, Thibaut Jean Pierre
Publisher: name: ETH Zurich
Year: 2018

description: In the last decades, a growing body of evidences of the influence of the need for social contacts on mobility, and in particular leisure mobility, has been accumulated. The idea that explicitly considering those motives in transport models could improve forecasts is making progress. However, the actual implementation of those ideas is still difficult, in particular due to the lack of data on how do individuals plan joint activities. 
This paper will report on analysis performed in this context, using data from the SensibleDTU data collection effort (Stopczynski et al., 2014), where smartphones with GPS tracking were provided to 1000 bachelor students over one year. This dataset is unique in the sense that it tracks mobility of a densely connected social network of substantial size over a long period of time. Using a anonymized extract of this data, the paper will focus on the properties of travel for meeting friends, focusing on the properties of the travel patterns of the participants. In particular, the hypothesis that party composition have a significant impact on the properties of travel will be tested.
An integrated simulation environment for autonomous mobility on demand in Zurich
Creators: name: Hörl, Sebastian
Publisher: name: ETH Zurich
Year: 2018

description: Over the course of the past two years research activities around fleets of automated vehicles have been conducted in the Swiss context. First, a thorough assessment of costs and prices of automated vehicles (Bösch et al., 2018) has been undertaken, including numerous factors from fuel to maintenance, dispatching and cleaning of the vehicles. Second, a stated choice survey has been conducted (Becker and Axhausen, 2017) which explores how people in the canton of Zurich, Switzerland would change their travel behaviour once a fleet of automated vehicles becomes available. Third, a simulation platform based on the agent- and activity-based simulation framework MATSim (Horni et al., 2016) has been developed that allows for the simulation of automated vehicle services with highly customizable fleet characteristics (Hörl, 2017). The paper will present the combination of those three components into an integrated simulation environment that allows for detailed demand estimation and assessment of future scenarios for Autonomous Mobility on Demand systems.
Quark deconfinement and implications for the radius and the limiting mass of compact stars

description: We study the consequences of the hadron-quark deconfinement phase transition in stellar compact objects when finite size effects between the deconfined quark phase and the hadronic phase are taken into account. We show that above a threshold value of the central pressure (gravitational mass) a neutron star is metastable to the decay (conversion) to a hybrid neutron star or to a strange star. The "mean-life time" of the metastable configuration dramatically depends on the value of the stellar central pressure. We explore the consequences of the metastability of ``massive'' neutron stars and of the existence of stable compact quark stars (hybrid neutron stars or strange stars) on the concept of limiting mass of compact stars. We discuss the implications of our scenario on the interpretation of the stellar mass and radius extracted from the spectra of several X-ray compact sources. Finally, we show that our scenario implies, as a natural consequence a two step-process which is able to explain the inferred ``delayed'' connection between supernova explosions and GRBs, giving also the correct energy to power GRBs.

Cryo-EM studies of CMG translocation and cohesin loading
Creators: name: Eickhoff, Carl Patrik
Publisher: name: Imperial College London
Year: 2020

description: Before mitosis, the genome must be replicated in the parental cell and sister chromatids must be tethered to ensure accurate division of genes between daughter cells. Within the replisome, DNA unwinding is facilitated by the CMG helicase which contains a hexameric ATPase motor encircling the leading strand template. Intriguingly, the helicase polarity, the mechanism of translocation and how CMG- bound replisome factors such as Mcm10, the MCT complex and Polε affect the helicase has remained elusive. Following replication, sister chromatids are tethered within a dynamic cohesin ring structure. Cohesin loading onto DNA requires ATPase activity and a separate loader complex but it has remained unclear how topological DNA entrapment is mechanistically facilitated or how cohesin engages DNA. In this study I have used cryo-EM together with biochemical assays to investigate how the CMG helicase unwinds DNA and how the cohesin complex is loaded onto DNA. First, I developed a fork affinity purification strategy to establish the binding and translocation polarity of CMG. I then determined the cryo-EM structure of fork-bound CMG, revealing several translocation states with the leading strand template bound to different helicase subunits around the ring. Together with ATPase active site mutations, these structures suggest a rotary but asymmetric translocation mechanism for the helicase. Further analysis of the larger replisome revealed that the MCT complex engages the N-terminal side of the helicase to stabilise parental duplex DNA prior to unwinding. In a collaborative project with Dr Torahiko Higashi, I also determined a cryo-EM structure of the DNA-engaged cohesin complex bound to the loader in a hydrolysis-independent pre-loading conformation. Supported by cross- linking mass spectrometry, FRET and other biochemical assays this structure represents an intermediate state in a two-step cohesin loading mechanism that is completed upon ATP hydrolysis and DNA entry into the cohesin ring.
On Abelian Multi-Chern-Simons Field Theories

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: In this paper a class of multi-Chern-Simons field theories which is relevant to the statistical mechanics of polymer systems is investigated. Motivated by the problems which one encounters in the treatment of these theories, a general procedure is presented to eliminate the Chern-Simons fields from their action. In this way it has been possible to derive an expression of the partition function of topologically linked polymers which depends explicitly on the topological numbers and does not have intractable nonlocal terms as it happened in previous approaches. The new formulation of multi-Chern-Simons field theories is then used to remove and clarify some inconsistencies and ambiguities which apparently affect field theoretical models of topologically linked polymers. Finally, the limit of disentangled polymers is discussed.

Joint probabilistic modelling of images and non-imaging covariates: a causal perspective
Creators: name: Coelho De Castro, Daniel
Publisher: name: Imperial College London
Year: 2020

description: Typical machine-learning tasks in imaging applications involve training a model to predict some target annotation (e.g. a class label) from an image. However, by neglecting valuable side-information that is often available in real-world settings, such models are vulnerable to confounding and may not generalise outside the lab environment. This thesis argues for the integration of causality into image analysis workflows, supported by the development of methodologies for jointly modelling images and non-imaging data, especially for healthcare applications. We first demonstrate that causal reasoning can shed new light on some of the greatest challenges in medical image analysis: data scarcity, i.e. the limited availability of high-quality annotated data; and data mismatch, whereby exogenous domain differences or sample selection may threaten the external validity of a predictive model. Turning to practical aspects of probabilistic modelling, we verify the suitability of nonparametric mixtures to modelling image intensities, and employ them in a novel intensity normalisation method. We then leverage similar techniques to develop a unified probabilistic model for a (benign) face recognition application, incorporating face features, unlimited identities, sparse and noisy name labels, and contextual side-information. To facilitate more general research into learning with heterogeneous data, we additionally introduce an experimental sandbox based on images of handwritten digits, including measurable shape attributes and controllable image perturbations. Finally, bridging causality theory and deep probabilistic modelling, we propose the framework of deep structural causal models, which offer tractable generative, interventional, and counterfactual capabilities for high-dimensional, heterogeneous data. Along with the increased robustness of models that can naturally integrate multiple sources of data, further considerations surrounding transparency, interpretability, explainability, and fairness make it clear that a causal perspective contributes towards building machine-learning systems that are not just highly performant, but also safe and reliable.
An Empirical Study of Parallelizing Test Execution Using CUDA Unified Memory and OpenMP GPU Offloading

Publisher: name: Zenodo
Year: 2021

description: The execution of software testing is costly and time-consuming. To accelerate the test execution, researchers have applied several methods to run the testing in parallel. One method of parallelizing the test execution is by using a GPU to distribute test inputs among several threads running in parallel. In this paper, we investigate three programming models CUDA Unified Memory, CUDA Non-Unified Memory, and OpenMP GPU offloading to parallelize the test execution and discuss the challenges using these programming models. We use eleven benchmarks and parallelize their test suites by using these models. Our study shows some limitations (e.g. cache size, branch divergence, and load imbalance) when using GPUs to execute the testing in parallel.

description: We report the multistep electrolytic process for the synthesis of high Tc single phase HgBa2Ca2Cu3O8+ (Hg-1223) superconducting films. The process includes : i) deposition of BaCaCu precursor alloy, ii) oxidation of BaCaCu films, iii) electrolytic intercalation of Hg in precursor BaCaCuO films and iv) electrochemical oxidation and annealing of Hg-intercalated BaCaCuO films to convert into Hg1Ba2Ca2Cu3O8+ (Hg-1223). Films were characterized by thermo-gravimetric analysis (TGA) and differential thermal analysis (DTA), X-ray diffraction (XRD) and scanning electron microscopy (SEM). The electrolytic intercalation of Hg in BaCaCuO precursor is proved to be a novel alternative to high temperature-high pressure mercuration process. The films are single phase Hg-1223 with Tc = 121.5 K and Jc = 4.3 x 104 A/cm2.

description: While cyclic scheduling is involved in numerous real-world applications, solving the derived problem is still of exponential complexity. This paper focuses specifically on modelling the manufacturing application as a cyclic job shop problem and we have developed an efficient neural network approach to minimise the cycle time of a schedule. Our approach introduces an interesting model for a manufacturing production, and it is also very efficient, adaptive and flexible enough to work with other techniques. Experimental results validated the approach and confirmed our hypotheses about the system model and the efficiency of neural networks for such a class of problems.
