description: Thermal power plants require water cooling pump stations to inject fresh water into the condenser. Generally, these pump stations have vertical mixed-flow pumps with large flows and low-to-medium heads that take water from rivers or reservoirs. Under certain natural conditions, water sources can reach extraordinarily low levels, thus affecting pump operation as the minimum recommended submergence might not be met, causing the power plant to be powered off. This causes both a very high loss of profit for the company and a decrease in the available power for the electrical supply system. Therefore, expanding the range of submergence under which pumps could be operated safely for special, transitory, and emergencies is an alternative worth exploring. Pump operation below the minimum level gives rise to unacceptable vortices on the free surface, air entrainment inside the circuit, higher mechanical vibrations, and lower efficiencies due to higher pre-swirl at the suction bell. Because of this, an anti-vortex device is proposed to prevent free surface vortex formation to allow the operation of the pump over a wider range of submergence. The device has a grating shape and was designed and optimized based on scale model tests performed on a typical pump bay following the ANSI standard intake design. Flow analyses through particle image velocimetry (PIV), acoustic Doppler velocimetry (ADV) velocity profiles, and swirl-meter measurements were carried out for a range of levels under the minimum and then compared with the device installed under the same conditions. Experiments proved the effectiveness of the solution to reduce free surface vortex formation and pre-swirl, allowing pumps to operate down to half of the recommended submergence.

description: Although the architecture competition has been analysed through a number of rhetorical lenses, the recurring production of transcultural metaphors, particularly in international competitions, remains to be addressed as a genuine disciplinary phenomenon. The hypothesis of competitions as contact zones is particularly appropriate for the study of international events, in which competitors forge broad analogical figures to bridge cultural differences. Recent studies in the cognitive understanding of analogical matrices have considerably reinforced the theories on metaphors. Our analytical grid characterizes analogical matrices to identify levels of symbolic operations through the differentiation of formal, structural and conceptual analogies. We first dig into a sample of competition projects nicknames (Crystal, Birds’Nest, DNA, Cloud, Lace, Stealth, etc.) to confirm that these tropes have a paradoxical status at the intersection of architects’ intents and the public expectations. We then summarize an in-depth hermeneutical discourse analysis of 40 North American international competitions. This indicates a fourfold series of expectations to which competitors hope to provide answers in an international ‘conflict of interpretations’. Adhering to the theory of speech acts, we suggest that performative metaphors in competitions appear less as indicators of designers’ intentions than as products of the broader context surrounding competitions themselves. We conclude with a proposed grid indexing four types of contact zones in which metaphorical relationships are actively created and not just repeated.

description: We study rational approximation properties for successive powers of extremal numbers defined by Roy. For $n\in{\{1,2\}}$, the classic approximation constants $λ_{n}(ζ),\hatλ_{n}(ζ),w_{n}(ζ),\hat{w}_{n}(ζ)$ connected to an extremal number $ζ$ have been established and in fact much more is known. However, so far almost nothing had been known for $n\geq 3$. In this paper we determine all classic approximation constants as above for $n=3$. Our methods will more generally provide detailed information on the combined graph defined by Schmidt and Summerer assigned to an extremal number, its square and its cube. We provide some results for $n=4$ as well. In the course of the proof of the main results we establish a very general connection between Khintchine's transference inequalities and uniform approximation.

description: Numerical modelling is an attractive alternative over physical modelling. However, sometimes both kind of techniques are coupled. This is the case of Hampaturi Dam in La Paz, Bolivia. A physical model was built for the optimization of the spillway. Hence, a numerical model was implemented with Delft3D computational model. Delft3D is a model based on two-dimensional flow equations (hydrostatic equations), and full three-dimensional equations (hydrostatic equations). Both modes were tested for the flow over the spillway, which includes a steep discharge channel that poses an additional difficulty. The goal of this research is to test the model (in both modes) on these flow conditions in order to determine the feasibility in applying Delft3D on this kind of structure. The model was calibrated and validated for both modes, hydrostatic and non-hydrostatic, by the variation of Manning’s roughness coefficient and eddy viscosity, reproducing the observed flow velocities and water depths. Following, a sensitivity analysis was carried out to determine the influence of different parameters in both modes, like: number of vertical layers, bed roughness and eddy viscosity. This analysis was executed by using an independent mesh solution. Results show a significant influence of the tested parameters. Then, the influence of the channel steepness on the performance of the model was tested. Results show that non-hydrostatic mode produces smooth flow profiles. Finally, it was observed that both modes can operate up to inclination angles of 60° for the discharge channel, setting an operation limit for Delft3D in this kind of structure.

description: For each valued quiver $Q$ of Dynkin type, we construct a valued ice quiver $Δ_Q^2$. Let $G$ be a simple connected Lie group with Dynkin diagram the underlying valued graph of $Q$. The upper cluster algebra of $Δ_Q^2$ is graded by the triple dominant weights $(μ,ν,λ)$ of $G$. We prove that when $G$ is simply-laced, the dimension of each graded component counts the tensor multiplicity $c_{μ,ν}^λ$. We conjecture that this is also true if $G$ is not simply-laced, and sketch a possible approach. Using this construction, we improve Berenstein-Zelevinsky's model, or in some sense generalize Knutson-Tao's hive model in type $A$.

Cross-linguistic Syntactic, Lexical and Phonetic Influence in the Acquisition of L3 Spanish
Creators: name: Llama, Raquel
Publisher: name: Université d'Ottawa / University of Ottawa
Year: 2017
Subjects: L3 Acquisition

description: The main ongoing debate within the recently-established field of Third Language (L3) Acquisition revolves around which of the previously-acquired languages prevails as a source of cross-linguistic influence (CLI) during production in the target language. Whereas several factors have been found to promote CLI, the existing body of L3 research points to a potential stronger rivalry between two of them: typology, or the relative distance among the languages involved, and second language (L2) status, also known as foreign language effect. In fact, they are at the core of two models of multilingual transfer that stem from the area of L3 morphosyntax, namely the Typology Primacy Model (TPM; Rothman, 2010, 2011, 2013, 2015), and the L2 Status Factor Model (L2 SFM; Bardel & Falk, 2007, 2012). For the most part, claims backing a more determinant role for typology come from studies investigating lexis. Whether or not typology overrides the effect of the L2 with regards to syntax and phonology as well is less clear. On the one hand, studies focusing on syntactic CLI can be divided into those whose findings suggest a crucial role either for the L1 (Na Raong & Leung, 2009) or for the L2 (Bardel & Falk, 2007), those in which findings point to typology as the deciding factor in determining a source of CLI (Rothman, 2011), and those that fail to show any influence from the L2 on the L3 (Håkansson, Pienemann, & Sayehli, 2002) even when the L2 and the L3 are typologically close (Martínez Adrián, 2005). On the other hand, results from previous research investigating phonological CLI also yield three main distinct findings: i) a more marked L2 effect (Llama, Cardoso & Collins, 2010), ii) a predominant influence from the first language (L1; Llisterri & Poch, 1987), and iii) combined CLI, that is, the L1 and the L2 concur in influencing the L3 (Wrembel, 2014). The primary goal of this dissertation is to add to the debate by looking into all three sub-areas among trilinguals at a high-intermediate to advanced level of proficiency, which has been the least targeted proficiency level until now. The selected topics, per area, are: lexical inventions, relative clause attachment preferences (RCA), and voice onset time (VOT). The secondary goal was to compare the relative influences of typology and L2 status across sub-areas, and to examine all results in light of three of the current L3 multilingual transfer models, the TPM, the L2 SFM, and the Cumulative Enhancement Model (CEM; Flynn, Foley, & Vinnitskaya, 2004). The results obtained are in clear agreement with previous reports in the area of lexis. However, the interplay of our trilinguals’ linguistic systems with regard to RCA and VOT is more complex. Findings in these areas seem to suggest that other factors (language exposure in the case of RCA, and the L1, in the case of VOT) may trump the two under investigation.

description: In the final years of the Estado Novo regime (1933–1974), the Amsterdam Town Hall International Competition of 1967 presents the opportunity for seven teams of Portuguese architects to confront their own reality and rehearse distinct visions of building and city. From a national context, politically and geographically distant from the heart of the disciplinary debate of the 1960s, the proposals submitted set the terms on which Portugal competes in Amsterdam, revealing in the diversity of approaches and experiences forwarded by this new generation of architects the vitality of Portuguese architecture on its path to internationalisation. This article retraces the Portuguese participation in the Amsterdam Town Hall Competition to refute the generalised idea of cultural mismatch with the European scene of the time and assesses the impact of this particular event on the transition of Portuguese architecture to international recognition, an impact that Portuguese architecture historiography has to this day completely ignored.

House Vision

Publisher: name: FOOTPRINT
Year: 2019

description: The design of the detached house has been at the core of architectural developments in post-Second World War Japan and the subject of a lively discussion among architects about what makes a good home at a particular moment. Alongside the continuous production of houses, architects actively proposed new ways of living that contrasted with what was increasingly becoming a uniform housing stock based on mass fabrication. However, the intensification of neoliberal policies after a decade of severe economic crisis in the 1990s drove architects towards social involvement once again, initiating a housing trend based on sharing, renovation and re-use of the existing housing stock. This essay will highlight the work of the House Vision think-tank and full-scale building exhibitions – initiated in 2011 by Japanese designer and art director Kenya Hara – as one response to the socio-economic and political conditions after the neoliberal turn. Similar to the efforts of independent architects in recent decades, House Vision aims to generate awareness in society about alternatives to mainstream housing options. Yet what makes this initiative different is that it is not an individual effort but a collaborative project between designers and industries to push the latest technologies in home electronics, energy and mobility devices into new architectural forms.

Structure-Function Relationships of Troponin in the Improvement of Cardiac Function
Creators: name: Cao, Tianxin
Publisher: name: University of Illinois at Chicago
Year: 2023

description: Cardiac function is vital for life. Heart failure (HF) caused by insufficient cardiac output to meet the systemic demand is the leading cause of death globally and lacks effective treatment. The contractile performance and energetic efficiency of cardiac muscle are key factors that determine cardiac function and efficiency. Cardiac muscle contraction and relaxation is regulated at the myofilament level by Ca2+ via the troponin (Tn) complex. Troponin T (TnT) is the tropomyosin (Tm) -binding subunit of Tn with a central role in anchoring Tn to thin filament and coordinating the Ca2+-modulated conformational changes. The structure and function of TnT are conserved in striated muscles of vertebrates and invertebrates. The N-terminal hypervariable region of vertebrate TnT is rich in Glu residues especially in cardiac T (cTnT) and avian flight muscle TnT. Insect TnT also has a Glu-rich long C-terminal extension. Our previous study suggested that the Glu-rich segment in the N-terminal variable region of avian pectoral muscle TnT binds Ca2+ with physiologically relevant affinity. My dissertation research will test a novel hypothesis that the Glu-rich segment segments of insect TnT, avian flight muscle TnT and cTnT may function as a myofilament Ca2+ reservoir/buffer near the Ca2+ receptor of Tn, Troponin C (TnC), for reducing the amounts of Ca2+ cycled during muscle contraction and relaxation and reducing ATP expenditure of the sarco(endo)plasmic reticulum calcium ATPase (SERCA) pumps to increase energetic efficiency of the muscle. We first studied this potentially novel mechanism in Drosophila model by deleting the Glu-rich C-terminal extension of TnT using CRISPR/Cas9 gene editing. Mutant Drosophila show significantly altered muscle and heart function, but their hearts exhibit a significantly higher tolerance to Ca2+-overloading produced by high frequency electrical pacing. It supports the myofilament Ca2+ reservoir function of the Glu-rich long C-terminal extension of insect TnT, potentially evolved for the high frequency asynchronous contraction of flight muscles. To test the hypothesis that the Glu-rich segment of TnT may function in improving the energetic efficiency of cardiac muscle in vertebrates, we constructed a CRISPR/Cas9 knock-in (KI) mouse model to replace the N-terminal variable region of cTnT with the 51 amino acid Glu-rich C-terminal extension of bee TnT. Cardiac functions were studied using isolated cardiomyocytes and ex vivo working hearts. In addition to better understand the structure-function relationship of TnT, the direct goal of my dissertation research is to explore the Ca2+ reservoir function of TnT evolutionarily selected for flight muscles as a new approach to improve cardiac muscle efficiency for the treatment of HF.
Hong Kong -- Shanghai Connect / Hong Kong -- Beijing Disconnect (?): Scaling the Great Wall of Chinese Securities Trading Costs

description: We utilize a fundamentally different model of trading costs to look at the effect of the opening of the Hong Kong Shanghai Connect that links the stock exchanges in the two cities, arguably the biggest event in international business and finance since Christopher Columbus set sail for India. We design a novel methodology that compensates for the lack of data on trading costs in China. We estimate trading costs across similar positions on the dual listed set of securities in Hong Kong and China, hoping to provide useful pieces of information to help scale 'The Great Wall of Chinese Securities Trading Costs'. We then compare actual and estimated trading costs on a sample of real orders across the Hong Kong securities in the dual listed pair to establish the accuracy of our measurements. The primary question we seek to address is 'Which market would be better to trade to gain exposure to the same (or similar) set of securities or sectors?' We find that trading costs on Shanghai, which might have been lower than Hong Kong, might have become higher leading up to the Connect. What remains to be seen is whether this increase in trading costs is a temporary equilibrium due to the frenzy to gain exposure to Chinese securities or whether this phenomenon will persist once the two markets start becoming more and more tightly coupled. It would be interesting to see if this pioneering policy will lead to securities exchanges across the globe linking up one another, creating a trade anything, anywhere and anytime marketplace. Looking beyond mere trading costs, such studies can be used to gather some evidence on what effect the mode of governance and other aspects of life in one country have on another country, once they start joining up their financial markets.

Context, Community, and Capital
Creators: name: Schindler, Susanne
Publisher: name: FOOTPRINT
Year: 2019

description: This essay focuses on the language architects use to navigate the intersection of architecture, housing, and neoliberalism. Schindler argues that terminology plays a powerful role in allowing architects to avoid the socio-economic assumptions embedded in their work. Schindler traces the emergence, evolution, and codification of two such terms, ‘context’ and ‘community’, and how they have frequently been conflated. She shows how they were central to New York City’s gradual shift from welfare-state to neoliberal housing policies between the mid-1960s and the present day by connecting them to a third key term, ‘capital’. The vest-pocket housing plan developed for the South Bronx as part of the federal Model Cities programme serves as a case study. In the Bronx, the triangulation of community, context, and capital led to new development models, as well as new housing typologies, including the large-scale rehabilitation of existing tenements and small-scale new construction of row houses. The resulting shift in architectural discourse, and the codification of these practices in zoning and tax laws, have remained in force in New York City to this day.

description: The safety of mobile robots in dynamic environments is predicated on making sure that they do not collide with obstacles. In support of such safety arguments, we analyze and formally verify a series of increasingly powerful safety properties of controllers for avoiding both stationary and moving obstacles: (i) static safety, which ensures that no collisions can happen with stationary obstacles, (ii) passive safety, which ensures that no collisions can happen with stationary or moving obstacles while the robot moves, (iii) the stronger passive friendly safety in which the robot further maintains sufficient maneuvering distance for obstacles to avoid collision as well, and (iv) passive orientation safety, which allows for imperfect sensor coverage of the robot, i. e., the robot is aware that not everything in its environment will be visible. We complement these provably correct safety properties with liveness properties: we prove that provably safe motion is flexible enough to let the robot still navigate waypoints and pass intersections. We use hybrid system models and theorem proving techniques that describe and formally verify the robot's discrete control decisions along with its continuous, physical motion. Moreover, we formally prove that safety can still be guaranteed despite sensor uncertainty and actuator perturbation, and when control choices for more aggressive maneuvers are introduced. Our verification results are generic in the sense that they are not limited to the particular choices of one specific control algorithm but identify conditions that make them simultaneously apply to a broad class of control algorithms.

description: In the modern times where cyber - attacks are increasing at an alarming rate. The key components of the internet that is the traffic needs to be secured. The internet traffic flows in the form of packets which travel from one destination to the other. The major cyber - attacks target these packets to compromise device and network security. The paper proposes a fortified technique of internet providing to any enterprise, organization or individual by providing a local server NATRAJ to which every device can make requests to and the requests are handled by NATRAJ in such a manner that the internal security of the network stays ensured. At last these requests can communicate with the outer network and NATRAJ acts like a firewall. The proposed idea according to the paper points towards assigning a unique hash value to every device, router and their respective send and get request made to the server. This hash table can be put into use to properly deliver the packets inside the internal networks and can be ensured secured against any internal network breaches. The hash provided requests can be processed through our neural network to check for malicious requests send or received as the other neural network can monitor the directed traffic. Both of the neural network systems can act like a two factor authentication system to cross verify the packets and the address to which they will be delivered and the entire system will act like a two factor authentication firewall for the internal network which will in last communicate with the outer network or internet.
The Value of Housing

description: This issue of Footprint brings together housing-as-design with housing-as-policy and housing-as-market to discuss what is, today, the value of housing. It discusses how the architecture of housing plays a role in changing behavioural norms and models of subjectivation promoted by the neoliberal ideological agenda. The contributions included in this issue examine different ways of addressing the production of housing either as a social right or a commodity, or both combined. Reviewing cases from North America, Europe and Asia, they discuss the extent to which the social and economic agendas of the public sector and the market determine the architecture of housing. The background of the discussion is defined by a deadlock: the architectural discourse calls upon the state to re-provide housing and solve the crisis, while the neoliberal state is not interested in commissioning housing. Against this background, this issue examines how the architecture discipline can engage in new ways of responding to the neoliberal state of affairs, examining the entwined relation between ‘architecture’ as a cultural product and ‘housing’ as a socioeconomic need.

description: In a moment in which the term Man, and the humanist tradition which followed from it, have been challenged in feminist, queer, poststructuralist, and postcolonial critiques, which questioned its nature, or even pondered if we are actually human, Footprint 25 seeks to add to these perspectives cases of what we call radical conditioning, in which some architectures bypass assumed values of humanism and operate under a wholly different set of values, emanating from industrial and post-industrial economies and its technological developments. Unfolding in the study of histories, architectural types, aesthetics, atmospheres, systems, and users, the research articles and visual essays included in this issue shed light on the many ways architects, advertently or inadvertently, coalesce with forces intending to condition humans. Ultimately, this issue questions how these spaces, in which humans and their artifacts interact in unprecedented ways, could provide architecture with the timely opportunity to challenge our anticipated redundancy, and reconsider its own humanism in order to charge it with new meanings.

description: Hadwiger's conjecture asserts that any graph contains a clique minor with order no less than the chromatic number of the graph. We prove that this well-known conjecture is true for all graphs if and only if it is true for squares of split graphs. This observation implies that Hadwiger's conjecture for squares of chordal graphs is as difficult as the general case, since chordal graphs are a superclass of split graphs. Then we consider 2-trees which are a subclass of each of planar graphs, 2-degenerate graphs and chordal graphs. We prove that Hadwiger's conjecture is true for squares of $2$-trees. We achieve this by proving the following stronger result: for any $2$-tree $T$, its square $T^2$ has a clique minor of order $χ(T^2)$ for which each branch set induces a path, where $χ(T^2)$ is the chromatic number of $T^2$.

description: The focal point of this essay is the turn from the display of objects to the display of environments, a change that blurs the line between the body and the display, and arguably absorbs the subject into the object. This turn is enabled by the digital age, as well as ‘the experience economy’, and is manifested in the rise of immersive display systems. The Selfie Museum epitomizes this cultural shift. In the Selfie Museum, subject and object aren’t the sole dichotomies that are conflated; physical space combines with the virtual image; the still moment merges in the temporal experience; and two-dimensional projections are overlaid onto three-dimensional structures. As a result, architects become ‘experience designers’, virtual reality is a mode of design practice, and an ‘instagrammable’ moment is a project deliverable. In this essay I simultaneously acknowledge these changes and critique them. At the same time, I offer the combination of apparent oppositions as a potential new set of tools that can help rethink aspects of the architecture discipline and profession. By studying the Selfie Museum as both an architectural typology and a socio-political entity, I challenge the traditional museum as an institution, classic body image perceptions, and the common concept of a tourist destination.

Kundera's Artful Exile: The Paradox of Betrayal

Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: The Czech novelist Milan Kundera who has lived in France since 1975 is all too familiar with betrayal, which punctuates both his life and his works. The publication of his novel The Unbearable Lightness of Being in 1984 sparked a heated debate among some of the most prominent Czech dissidents at home and leading Czech intellectuals in exile. Accusations of betrayal leveled against the author are central to the polemic, but the main area of contention addresses the larger questions of the role, rights, and freedoms of a writer of fiction, as expressed by two branches of Czechoslovak culture: exilic and dissident. By examining the dispute surrounding Kundera's best-known novel and tracing the trajectory of the betrayals he allegedly committed in exile, I seek to investigate the broader philosophical issue of a novelist's freedom, to delineate the complexities of an exilic writer's propensity to betray, and to demonstrate, using Kundera's own conception of the novel as a genre, that his betrayals are in fact positive, liberating, and felicitous.

description: As the technology node of VLSI designs advances to sub10 nm, two interconnect-centric metrics of a circuit, the interconnect complexity (either number of interconnects or wirelength/WL) and congestion, become critically important across all design stages alongside conventional resource or function-unit (FU)-centric metrics like area/number-of-FUs and leakage power. High Level synthesis (HLS), one of the earliest and most impactful design stages, rarely monitors interconnect metrics, which makes their recovery at later stages very difficult. HLS algorithms and tools typically perform FU-centric minimization via operation scheduling, module selection (SMS) and binding. As a consequence, it mostly overlooks interconnect-based metrics. In this paper, we explore whether this can adversely affect interconnect metrics, and in general explore the correlation between FU-centric optimization in SMS, and the resulting interconnect metrics co-optimized (along with FU metrics) in the later binding stage(s). For this purpose we develop a probabilistic analysis for post-scheduling binding to estimate interconnect metrics, and verify its accuracy by comparison to empirical results across different scheduling techniques that generate different degrees of FU optimization. Based on both empirical and analytical results we predict how interconnects metrics will pan out with different degrees of FU optimization. Finally, based on our analysis, we also provide suggestions to improve interconnect metrics for whatever FU optimization degree an available SMS technique can achieve.

description: The emergence of financial institutions such as the exchanges or bourses of northern Europe in the sixteenth and the seventeenth centuries made possible the emergence of speculation in financial instruments. Speculation evolved into a game with its own logic, and the implied ethos of the speculator prioritised abstract notions and self-interest. This article investigates the relation between this ethos of speculation and architecture in this timeframe. During this period, the architecture of the exchanges transformed; what was a square with an inside at the outset gradually became an enclosed institution with representative façades toward the end of the period. The transition of the physical environment of exchange and the increasingly complex financial instruments interact, and this interaction is traced through a sequence of exchange-structures inspired by one another. The question explored is: what is the relationship between the emergence of an ethos of speculation and the architectural space of the exchange? This relationship can be discussed in terms of a different kind of conditioning that has less to do with industrialisation, but which could, in extension, form a starting point for discussions on architecture’s role in the formation and conditioning of homo œconomicus.

description: It has been recently suggested~\cite{Berezhiani:2015yta} that emerging tension between cosmological parameter values derived in high-redshift (CMB anisotropy) and low-redshift (cluster counts, Hubble constant) measurements can be reconciled in a model which contains subdominant fraction of dark matter decaying after recombination. We check the model against the CMB Planck data. We find that lensing of the CMB anisotropies by the large-scale structure gives strong extra constraints on this model, limiting the fraction as $F<8\%$ at 2\,$σ$ confidence level. However, investigating the combined data set of CMB and conflicting low-$z$ measurements, we obtain that the model with $F\approx2\!-\!5$\% exhibits better fit (by 1.5-3\,$σ$ depending on the lensing priors) compared to that of the concordance $Λ$CDM cosmological model.

Action Office, or, Another Kind of ‘Architecture Without Architects’
Creators: name: Denny, Phillip

description: When Robert Propst set out to transform the white-collar office, he began with a research protocol: observe, notate, quantify, represent. This process, based equally on the production of data and the use of representation to turn that data into information, led to Action Office, a system that aimed to transform every action and surface of the office environment into a data-rich cybernetic loop. For Propst, the key to turning the office into a space that produced information, rather than merely managed it, was display; as he wrote, ‘Action Office 2 provides no place for paper to hide or die – all paper material is displayed. You can see it, it is all signalled or marked and it will feed back a strong purge signal when it becomes overabundant.’ Propst’s Action Office system mobilised display to produce an information environment that cuts out noisy signals to frame clear communication.

Agricultural Economics in Extension

Subjects: Teaching/Communication/Extension/Profession

description: Summary: Economic changes have made farming more complex and business management factors more important in present day farming. Changes in economic conditions, such as price changes, changes in demand, changes in marketing costs, changes in tariffs and other national and international policies may be expected to create a continued increase in the demand for economic information that will permit the careful planning of the whole farm business by farmers on the basis of increased farm income. County agents arc to be commended in the way they are meeting this now challenge. Not only are many of them giving more attention to the local interpretation and adaptation of economic information, but they are also developing new methods and uncovering additional leadership for a wider projection of the full program. The important problem at this time is in finding ways and means of further assisting county agents to meet the increased demand of farmers for economic information.

title: Stilling Basins Using Wedge-Shaped Baffle Blocks

description: The United States Bureau of Reclamation (USBR) extensively studied hydraulic jump-type stilling basins for various inflow and tailwater conditions. They recommend Basin III using chute blocks, rectangular baffle blocks, and sloping end sill for medium to high dams. However, a significant contribution to the knowledge regarding the production of turbulence in discontinuity layers, the dissipation of energy, the convection, and the decay of turbulence in hydraulic jump was made by subsequent researchers. However, while developing the stilling basin, the wake formed by the jets separating at the front corners of the rectangular baffle blocks in Basin III and reattaching the downstream of the blocks was not considered. The use of Basin III was found limited to lower dams since cavitation of the baffle blocks was observed in many dams. After that, the use of wedge-shaped baffle blocks below a model spillway was systematically investigated. It was noticed that baffle blocks with a vertex angle of 1200 cut back at 900; the separating jets do not reattach downstream. Due to the wedge shape (super-cavitating), the low-pressure cavities do not collapse on the boundary. The new forms of baffle blocks are found to offer more drag to the flow when compared to rectangular blocks. Model tests were conducted to evolve stilling basins using the new baffle blocks and were highly successful. For example, in a stilling basin with an Inflow Froude Number of 7.07, with new blocks, a floor-length of about half the earlier suggested length is found to have better characteristics of scouring and sweep-out depth as compared to USBR Stilling Basin III.

description: Design of stilling basins for the dissipation of energy has been established by the seminal tests developed by the U.S. Bureau of Reclamation and the Saint Anthony Falls Laboratory, by mid XX century. Such designs basically include blocks and end sills, dentated or complete. However, those designs need variations in desertic zones, where the end sill is not allowed due to self-cleaning purposes, and no “drop” is possible for the same reason. In the case of the outlet structure for Perris Dam, located in the Riverside County, California, the design of the stilling basin was optimized using a Computational-Fluid-Dynamics (CFD) approach, and a physical model. Potential overspill due to unsteady oscillations of the free surface and energy dissipation were studied using a Volume of Fluid (VoF) method combined with a RANS turbulence closure, and then validated with a physical model. The combination of powerful numerical simulations with experimental models allows for an efficient analysis and design of complex hydraulic structures. The cheaper numerical simulations provide an accurate description of the flow that can be used to test several geometries and evaluate the most suited one to be represented on the physical model. From this first stage, an optimized geometry is implemented in a physical model which is used to calibrate and validate the numerical simulations as well as to optimize the geometries obtained from the numerical model. The new proposed structure promoted a high level of dissipation and a design that reduce the maintenance issues associated with desertic regions.

description: Measurements in aerated high-velocity spillway flows have been traditionally conducted with point-source instruments. LIDAR is a promising remote sensing technology that may be able to provide more detailed insights into the free-surface properties. So far only one laboratory study has investigated the use of LIDAR technology in air-water flows on a spillway model showing that free-surface data in the aerated part of the flow can be recorded with high spatial and temporal resolution. However, the spillway model, as well as the aerated flow region, were quite short and further research is needed to test the performance of LIDAR technology on a longer spillway. Herein, the present study tested a LIDAR in an 8.6 m long laboratory spillway with strip roughness. To ensure consistency of results along the spillway, the performance of the LIDAR was first assessed without flowing water along a straight wall as well as in the spillway model without water. The results showed that the LIDAR was affected by viewing angle that can be corrected using a scaling factor. The LIDAR was subsequently used to measure the free-surface properties of skimming flows. Comparative results for three different LIDAR measurement positions showed effects on the free-surface elevations and standard deviations linked with the different grazing angle of the LIDAR relative to the free-surface and with the waviness of the free-surface. A potential correction scheme for this is discussed.
