Numerical analysis is used to examine the unsteady MHD free convection and mass transfer fluid flow through a porous medium in a rotating system. Impulsively started plate moving its individual plane is considered. Similarity equations of the corresponding momentum, energy, and concentration equations are derived by introducing a time dependent length scale which infect plays the role of a resemblance parameter. The velocity component is taken to be inversely proportional to this parameter. The effects on the velocity, temperature, concentration, local skin-friction coefficients, Nusselt number, Prandl number, Dufour, Soret number and the Sherwood number of the various important parameters entering into the problem separately are discussed with the help of graphs.

layer stream and warmth exchange of an incompressible digression hyperbolicnon-Newtonian liquid from a
non-isothermal wedge in the nearness of attractive field. The changed preservation conditions are understood
numerically subject to physically fitting limit conditions utilizing a second-arrange precise verifiable limited
distinction Keller Box method. The numerical code is accepted with past studies. The impact of various rising
non-dimensional parameters, to be specific Weissenberg number (We), power law record (n), blended
convection parameter, weight angle parameter (m), Prandtl number (Pr), Biot number, attractive parameter
(M)and dimensionless extraneous direction on speed and temperature development in the limit layer
administration are inspected in subtle element. Moreover, the impacts of these parameters on surface warmth
exchange rate and nearby skin erosion are additionally examined. Approval with prior Newtonian studies is
introduced and amazing relationship accomplished. It is found that speed is lessened with expanding We,
while, temperature is increased. Expanding n improves speed yet diminishes temperature, a comparable
pattern was seen. An expanding M is found to decline speed however temperature increments.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Abstract : The numerical studies are performed to examine the mass transfer flow with thermal diffusion and
diffusion thermo effect past an infinite, inclined vertical plate in a porous medium in the presence of chemical
reaction. First of all, the governing equations are transformed to a system of dimensionless coupled partial
equations. Explicit finite difference method has been used to solve these dimensionless equations for momentum,
concentration and energy equations. During the course of discussion, it is found that various parameters related
to the problem influence the calculated result. Finally, the profiles of velocity, concentration and temperature
are analyzed and illustrated with graphs.
Keywords: Chemical Reaction,Dufour effect, Finite Difference Method, Inclined infinite plate, Soret effect.
I. Introduction
Effect of heat and mass transfer on fluidshas become important through the last few years due to a
number of industrial processes and engineering applications which experiences not only temperature difference
but also concentration difference . In many mass transfer processes, heat transfer considerations arise owing to
chemical reaction and are often due to the nature of the process. In processes such as drying, evaporation at the
surface water body, energy transfer in a water cooling tower and the flow in a desert cooler heat and mass
transfer occur simultaneously. In many of these processes, the determination of the total energy transfer, natural
convection processes involving theconvection along with inclined plate has received less attention than the cases
of vertical and horizontal plates. But natural convection processes involving the combined mechanism are
encountered in many natural processes, in various industrial applications involving solutions and mixtures in an
infinitely large inclined surface in absence of an externally induced flow and in different chemical processing
systems.
Sparrow and Cess [1] studied the free convection fluid flow past a semi infinite vertical plate in two
dimensions where buoyancy and magnetic forces acted simultaneously. The study of natural convection flow of
inclined plate is presented by the authors Ganesan and Palani [2, 3] and Sparrow and Husar [4].Dufour and
Soret effects on steady MHD free convection and mass transfer fluid flow through a porous medium in a
rotating system have been investigated by N. Islam and M. Alam [5].
Motivated by all these studies, we have had our research on the result of chemical reaction on unsteady
boundary layer flow with Soret and Dufour effect in a porous medium past through an inclined infinite plate.To
solve the problem numerically, governing partial differential equation has been transformed into non-similar
coupled partial differential equation by usual transformation. These equations has been solved numerically by
FORTRAN-95 and effects of parameters such as Dufournumber, Soret number and chemical reaction parameter
on velocity, temperature and concentration profile have been illustrated by graphs.

II. Mathematical Formulation
An unsteady, Two dimensional, laminar boundary layer flow of an incompressible, viscous, radiating
Boussinesq fluid near impermeable inclined vertical plate stretching with velocity U , temperature distribution
wT and concentration distribution wC is considered, in the presence of thermal diffusion (Soret) and diffusion-
thermo (Dufour) effects. The positive X coordinate is
measured along the plate in the direction of fluid motion and
the positive Y coordinate is measured normal to the plate.
Now, under the usual Boussinesq’s and boundary layer
approximations, the governing equations for the flow field
under consideration are

III. Numerical Solution
To solve the non-dimensional system by implicit finite difference method, a set of finite difference
equations is required. For this reason the area within the boundary layer is divided by some perpendicular lines
ofY axis as shown in Fig.2. It is assumed that the maximum length of boundary layer is 25MaxY . i.e. Y varies
from 0 to 25 and the number of grid spacing in𝑌directions is ( 100)n Hence the constant mesh size along Y-axis
becomes 0.25 (0 25)Y Y with a smaller time step 0.005t .
Let U , T and C denotes the values ofU , T and C at the end of the time-step respectively. Using
implicit finite difference, the following appropriate set of finite difference equation is obtained as;

V. Conclusions
In this research, the implicit finite difference solution of unsteady viscous, incompressible boundary
layer flow of a fluid has been investigated. The physical properties are illustrated graphically for different values
of corresponding parameters. Among them some important findings of this investigation are mentioned here;
1. Velocity profile shows decreasing effect with the increase of inclination (𝛼) and permeability
parameter (𝐾).
2. Temperature profile shows decreasing effect with the increase of Prandtl number (𝑃𝑟 )and Grashof
number (𝐺𝑟 )but increasing effect for Dufour number (𝐷𝑢 ).
3. Concentration profile shows decreasing effect with the increase of chemical reaction parameter
(𝛾)and Schimidt number (𝑆𝑐) but effect is so minor to study in case of Soret number (𝑆𝑜 ).
