Methods for Convex and General Quadratic Programming∗ Philip E. Gill† Elizabeth Wong† UCSD
Department of Mathematics Technical Report NA–10–01 September 2010 Abstract Computational
methods are considered for finding a point that satisfies the secondorder necessary conditions for a
general (possibly nonconvex) quadratic program (QP). The first part of the paper defines a
framework for the formulation and analysis of feasible–point active–set methods for QP. This
framework defines a class of methods in which a primal–dual search pair is the solution of an
equality–constrained subproblem involving a "working set" of linearly independent constraints. This
framework is discussed in the context of two broad classes of active–set method for ... Show more

This reformulation gives the primal–dual search pair as the solution of a KKT–system formed from
the QP Hessian and the working–set constraint gradients. It is shown that, under certain
circumstances, the solution of this KKT–system may be updated using a simple recurrence relation,
thereby giving a significant reduction in the number of KKT systems that need to be solved. The
linear constraints of a QP may include an arbitrary mixture of equality and inequality constraints,
where the inequality constraints may be subject to lower and/or upper bounds. Many mathematically
equivalent formulations of the constraints are possible, and the choice of formulation often depends
on the context. We consider the generic quadratic program minimize n x∈R 1 ϕ(x) = cTx + 2 xTHx
subject to Ax = b, Dx ≥ f, (1.1) where A, b, c, D, f and H are constant, H is symmetric, A is m × n,
and D is mD × n. (In order to simplify the notation, it is assumed that the inequalities involve only
lower bounds.) However, the methods to be described can be generalized to treat all forms of linear
constraints. No assumptions are made about H (other than symmetry), which implies that the
objective ϕ(x) need not be convex. In the nonconvex case, however, convergence will be to local
minimizers only. In Section 4, the nonbinding direction method is extended to problems

The goal of this paper is to bring Linear Algebra and Digital Signal Processing together for
efficiently solving the applied signal processing problems. Linear Algebra tool box is created to
visualize the signal by just clicking and dragging the concerned module. In MATLAB and other
platforms, tapping of the signals cannot be done and conventional code has to be written for solving
the problem. GNU Radio is a freeware software for processing signals through which tapping of
signal can be done .The module is created in GNU Radio with predefined template and the platform
used here is C++.Further, the code is glued to Python using swig. The blocks are created in order to
estimate energy, check orthogonality, compute unit normalization, find Euclidean norm of a signal
and least square fitting. The end user can visualize the signal in various plots. KEYWORDS: Linear

5. Description Of The Reference Voltage Vector
Referring to Fig. 1(ii), consider in region II, the reference voltage vector is following the arc x1x2 at
a particular modulation index m. The position of the reference voltage vector is shown in Table 1. It
shows that, depending on modulation index value, the duration of stay within subsector 1 and
subsector 2 changes. Similarly, consider in region III, the reference voltage vector is following the
arc y1y2 at aparticular modulation index. The position of the reference voltage vector is shown in
Table 1 and it shows that depending on the modulation index value, the duration of stay within
subsector 2,3 and 4 changes.
Table 1: Duration of stay in subsectors
Region Duration of stay in subsectors Angle information
II Subsector 1 0≤θ≤θ_R2 θ_R2= sin^(–1)
((1–√(12m^2–3))/4m) Subsector 2 θ_R2≤θ≤π⁄3–θ_R2
Subsector 1 π⁄3–θ_R2≤θ≤π⁄3
III Subsector 3 0≤θ≤θ_R3 θ_R3= sin^(–1)
((√(12m^2–3)–1)/4m) Subsector 2 θ_R3≤θ≤π⁄3–θ_R3
Subsector 4 π⁄3–θ_R3≤θ≤π⁄3
As the reference voltage vector is formed using discrete switching vectors, the operating voltage
vector does not follow the reference trajectory []. The deviations between applied switching vector
and reference voltage vector results in the ripple in the output current waveform. For any switching
instance, the instanteneous current ripple due to application of ith switching vector (i.e. application
corresponding voltage vector Vi) can be written as (d(ΔI) ⃗)/dt= 1/L⌊□((V_i ) ⃗ )–(V_ref ) ⃗⌋ (1)

individual? Discuss the role of the leader in initiating and managing change.
Answer
The Tata Group transformation can be greatly attributed to the vision and execution of Ratan Tata.

Tat managed to streamline the Tata Group. What advantages and disadvantages did the group gain
through the streamlining of business? Do you think, as of 2009, the Group is still present in too
many businesses?
Answer
There were a total of 84 companies in several industries under the Tata Group in the early days.
With the vision of the new leader, he realized that there was a lot of irrelevant businesses in the
group that did not contributed much to the group's profits and as a result he streamed line and exited
a lot of the industries in which the group was not doing well, in order to accomplish his vision and
goal and make the group stronger. In my opinion, this was a good move as the benefits outnumbered
the disadvantages. The stream lining made it possible for the group to manage the companies easier.
In addition, they were able to cut costs by having a smaller workforce and fewer overheads.
Importantly, they improved productivity in the group by eliminating some unnecessary ventures and
focusing more resources in certain areas, thus improving revenue. Finally, they were able to gain
profits from the sale of some companies. On the other hand however, this stream lining caused many
individuals to lose their jobs, resulting in a lot of homes having decreased incomes. There were also

happens is when a business completes a transaction, they then receive an email with a request to

CHAPTER 1
INTRODUCTION
Definition of Differential Equation
A differential equation is an equation which consists of derivatives or differentials of one or more
dependent variables with respect to one or more independent variables (Abell & Braselton, 1996).
Differential equation generally can be classified into two, which are ordinary differential equation
and partial differential equation. If a differential equation consists of ordinary derivation of one
dependent variable with respect to only one independent variable, it is known as ordinary
differential equation. Meanwhile, if a differential equation consists of partial derivative of one or
more dependent variables with respect to more than one independent variable, it is known as partial
differential equation.
Ordinary Differential Equation
In general, an ordinary differential ... Show more content on Helpwriting.net ...
It is simply expressed as the matrix product of two factors, a variable vector with a constant matrix,
x ̅(t)=Hv ̅(t) 1.6
, where H is a constant matrix and v ̅(t) is a time–variable vector. This approach, using the matrix
theory, gives a numerical solution to the systems of homogeneous or non–homogeneous of linear
differential equation with constant coefficient. Any systems of linear differential equation which can
be solved by Laplace Transformation can also be solved by this approach.
Problem Statement
The basic approach recalculates the partial fraction expansion coefficients of a rational function
from the very beginning whenever the initial conditions are changed, which is very time–
consuming. This study finds an alternative approach to compute the solution with a minimal and
straightforward effort of re–computation upon the initial conditions changed.

Mathematics widens the mind to think critically. It is more than measuring, counting and computing.
It opens up other subjects– sciences. As far as Mathematics teaching is concerned, the major goal is
the involvement of the students in the practice of realizing mathematical ideas and framing process.
One of the encouraging worries about learning Mathematics is the point that it opens up the mind to
solve problems that require radical order rational skills. These complications and puzzles provoked
the curiosity and challenge the inventiveness of individuals. Giving problem solving into the class
improves students' skills and their ability to reason prudently, rationally and creatively. Hugar
criticizes the things we might consider about a mathematics class are processes, equations, and word
problems, of which learning them, a student has to master to solve problem. Therefore, in the last
decades there has been a move to approach the teaching of mathematics through solving of problem.

a problem is situation, quantifiable or else that challenges a person or groups of people, which needs
determination, and for which the individual sees no seeming path to the solution. There are many

The Government of Trinidad and Tobago has decided to construct a new school at the beginning of
the year 2016. This is due as the island is ranked sixty–fourth (64th) in the Global Education Index
(United Nations Development Programme 2013) and there is a drive to increase the island's global
ranked by the Education Ministry of Trinidad and Tobago. As a result, they have authorized a formal
report to determine potential sites that the school can be built on in which official bodies will
investigate further. To accomplish this goal, applications of Geographic Information Systems were
utilized to assess land suitability in Trinidad with several criteria provided by the Government along

22. Forecasting By Vector Autoregression Models
CHAPTER NINE
FORECASTING BY VECTOR AUTOREGRESSION MODELS
9.1 Vector Autoregressive (VAR) Models
Vector Autoregression (VAR) models were introduced by the macro– econometrician Christopher
Sims (1980) to model the joint dynamics and causal relations among a set of macroeconomic
variables. The vector autoregression (VAR) is commonly used for forecasting systems of interrelated
time series and for analyzing the dynamic impact of random disturbances on the system of variables.
The VAR approach sidesteps the need for structural modeling by treating every endogenous variable
in the system as a function of the lagged values of all of the endogenous variables in the system.
The vector autoregression (VAR) model is one of the most successful, flexible, and easy to use
models for the analysis of multivariate time series. It is a natural extension of the univariate
autoregressive model to dynamic multivariate time series. The VAR model has proven to be
especially useful for describing the dynamic behavior of economic and financial time series and for
forecasting. It often provides superior forecasts to those from univariate time series models and
elaborate theory–based simultaneous equations models. Forecasts from VAR models are quite
flexible because they can be made conditional on the potential future paths of specified variables in
the model.
In addition to data description and forecasting, the VAR model is also used for structural inference
and policy analysis. In structural

Conservation of Linear Momentum
Objective
The primary goal of this experiment was to study the force that a jet generates on hemispherical,
flat, and conical surfaces. Further, the experiment exposed students to the concept of linear
momentum conservation by observing forces that a jet of water exerts on objects with different
shapes.
Results and Graphs Figure 1: Forces Acting on the x and y axis
As can be seen, the forces that act on the x–direction are caused by pressure at sections 1 and 2.
Similarly, an expression that relates the conservation of linear momentum in the Y– direction can be
developed.
Discussion
Although the experiment was successful, some errors occurred during the experiment that made
most values to deviate from the expected ones. Generally, both fixed and random errors were
observed (Mitchell & Worledge, 2015). The random errors, in this case, resulted into statistical
fluctuations in the measured data because of the limitations in precision measurement. Additionally,
the random errors occurred due to inability to take the same measurements as the expected ones.
Furthermore, fixed errors were responsible for reduced inaccuracies in the values obtained (Valiani

26. Video Games Are The Most Revolutionary Form Of Art
To quote the famous game designer Santiago Sir "Games are not just art, they are the most
revolutionary form of art mankind has ever known about". Video games are a hybrid form of art that
brings together multiple forms of art. Video games are very aesthetic. They achieve this through the
use of their realistic graphics, in depth development of the story, and the emotional attachment built
overtime with the game. Video games have come a long way in the development of the graphics
system. To really understand the substantial innovations that have been made, one needs to
understand where the original graphics started. The original video games used vector based
graphics, which uses geometric primitives to produce an image. This was common for arcade
games. These vector based graphics were mainly two dimensional and had little detail. For the time
that these games released it was an amazing feat of art that they could use math to produce these
images and have a reaction through the use of a joystick and buttons. Video games of the modern
time we live in have blown this feat of the past out of the water. The common form of producing
graphics in a video game now uses resolution based bitmap graphics to develop images. These
image can be three or two dimensional and have detail down to a bead of sweat rolling down your
cheek or the swift movement of the grass and landscape. Skyrim is a modern day video game that

Sytech– Curing the future
The history of SyTech and Gene therapy
Gene therapy was introduced in 1985 by SyTech and has been the main priority of the company ever
since due to its promising future in science. One of the first human gene therapy procedures
involved injecting the correct ADA gene to a four year old girl with the ADA deficiency. Due to the
success of the procedure, the patient is now living a healthy life. The success marked an important
landmark in human history, one that has the potential to change the future. What is gene therapy?
In short, gene therapy is a method in which DNA Is used to fix a genetic problem. These problems
can include missing or genes that don't work. The right genes are delivered to the cell via harmless
viruses for their provirus properties. The viruses then insert the good copy of the gene into the
patients DNA where the cells machinery reads the information like a manual and makes RNA
proteins so when it divides, ideally, the problem will be fixed. There are two types f gene therapy:
Germline (targets egg/sperm cells; stops disease in its tracks) and somatic (targets somatic cells;
after the disease is active).The methods for gene therapy that are being tested include:
Replacing the non working copy of a gene with a healthier one
Bringing new genes entirely for those that don't exist
Bring a new gene to fight/fix the disease.

Crispin, by Avi, takes place during the Middle Ages–the Medieval era. Living during this period also

unless you were born into a family of nobles, you were a powerless peasant. In the novel, Crispin is
a serf, the lowest rank of peasants, and suffers from many hardships because of it. With being serf,
your rights are stripped away from you, leaving you completely powerless. Masters are allowed to

It is the simplest technique ,with good dynamic performance , robust and gives large benefits. It is
recognized as an alternative method to field oriented control (FOC). Industrial drives with DTC are
present in the market today.DTC is proposed to control electromagnetic torque and stator flux by
directly modifying the stator voltage in accordance with the torque and flux errors DTC has added
advantages over FOC absence of mechanical transducer, no requirement of co–ordinate
transformation ,and a very simple control scheme with less computational time Though DTC is
simple and have fast transient response, it generates high level common mode voltage variations. To
avoid the problems of common mode voltage variations a new DTC algorithm was developed, in
which, only odd or only even voltage vectors will be applied in each sector in which stator flux lies
without using any zero voltage vectors. However, this method gave torque ambiguity. To overcome

different aspect ratios provided by the device in hand may lead to better compositions in the image.
The difficulties with aspect ratio are that when there is an inconsistency, one must either crop the

Here, we show how the ideas of tangent and normal vectors and curvature can be
used in physics to study:
The motion of an object, including its velocity and acceleration, along a space curve.
VELOCITY AND ACCELERATION
In particular, we follow in the footsteps of

50. VELOCITY & ACCELERATION
Example 3
It follows: v(t) = 2t2 i + 3t2 j + t k + i – j + k
= (2t2 + 1) i + (3t2 – 1) j + (t + 1) k
VELOCITY & ACCELERATION
Example 3
Since v(t) = r'(t), we have: r(t) = ∫ v(t) dt
= ∫ [(2t2 + 1) i + (3t2 – 1) j + (t + 1) k] dt = (⅔t3 + t) i + (t3 – t) j + (½t2 + t) k + D
VELOCITY & ACCELERATION
Example 3
Putting t = 0, we find that D = r(0) = i.
So, the position at time t is given by: r(t) = (⅔t3 + t + 1) i + (t3 – t) j + (½t2 + t) k
VELOCITY & ACCELERATION
The expression for r(t) that we obtained
in Example 3 was used to plot the path of the particle here for 0 ≤ t ≤ 3.
VELOCITY & ACCELERATION
In general, vector integrals allow us to recover:
Velocity, when acceleration is known

Also, researchers increasingly sought to automate the process and enhance the sophistication of

The work by Haeberli[2] enabled people to transform photographs into impressionist paintings with
minimal labor. The user clicked on a photo, and the underlying system automatically placed the
virtual strokes by using the color of the source image. They also added noise to results to enhance
the impressionist effect. However, the first automatic solution was a tool proposed by Litwinowicz
[3]. This is the paper which we review first in this report.
Processing Images and Video for an Impressionist Effect
This paper aims producing impressions of the original image, i.e. images that give a sense of an

they have been hand–painted. They produce painterly animation from video clips automatically after
the user specifies a few parameters to generate he first frame. After the user's preferences are taken
into account and he approves the first frame, the whole video segment is automatically produced
without further user intervention.
The biggest challenge in videos is to produce a temporally coherent style of animation which avoids
flicker and takes into account the movement of objects in the video. This paper was the first one to

The Usefulness of Viral Vectors in Treating Dravet Syndrome
Voltage–gated sodium channels initiate the development action potentials in neurons; mutations of
genes encoding these channels are responsible for genetic epilepsy syndromes with varying degrees
of severity1. Dravet syndrome, or severe myoclonic epilepsy of infancy (SMEI), is a complex and
severe form of childhood epilepsy, caused by a nonsense mutation in the sodium voltage–gated
channel alpha subunit 1 (SCN1a) gene. Severe loss of function mutation in Nav1.1 causes SMEI,
which involves intractable epilepsy, ataxia, and cognitive impairment 1. It is important to study this

Adeno–associated viral vectors (AAV):
Adeno–associated viral vectors are non–enveloped single stranded DNA viruses used in treating
diseases of the central nervous system 3. AAV vectors have been widely used in clinical trials to
deliver therapeutic genes to mutated ones, and are efficient and safe in vivo application3. However
one major drawback is the limited packaging capacity for genes with larger sizes 3. Fortunately, this
can be overcome with the treatment of the dystrophin gene (DMD), which encodes the cohesive
protein dystrophin that supports the cytoskeleton of a cell3. There are two methods can be used with
AAV vectors to decrease the duration of epilepsy: inducing somatostatin into AAV vectors and direct
injection of glial targeting AAV vectors.
Method 1:
Somatostatin (SST) is a neuromodulator known to have diverse functions in sleep and motor activity
and it plays a putative anticonvulsant role, such as in maintaining hippocampal homeostasis4. Some
studies have suggested that AAV vector–mediated expression of SST suppresses hippocampus
related seizure development in rats4. Viral vector gene therapy using SST as an anti–seizure–related
neuropeptide in a kindling model of epilepsy was implemented, where over successive electrical

development in order to maximize group effectiveness and efficiency. There are several different
models for small group development, but Tuckman 's model is "probably the most famous

Of great value at this stage is encouragement and patience. The reason for the conflict is generally
insecurity (Bonebright, 2010, p. 114), so providing a strong support system an reassurance can help
move a group to the next phase.
As members of the group begin to feel safe and secure, the conflict will settle and the group will
develop a bond and unified goals. Labeled a period of norming, it is "characterized by close
relationships and cohesiveness" (Group Development, 2003). In fact, this stage is so characterized
by relationship that it could almost be viewed as a honeymoon phase. Group members will
frequently set aside differences and unity becomes a priority. It is important at this stage to
emphasize honesty and creativity because the group will likely be trying so hard to be amenable that
some members may hold back. Others will be ready to open up given their newfound sense of
security within the group. This is also a critical time for the group because it typically delineates a
time to commit (Johnson & Johnson, 2016). If a group reaches this stage and not all members are on
board, it may hinder progress.
Once a group has developed cohesiveness, it will truly begin to produce. This phase of effectiveness
is titled performing according to Tuckman 's model. At this stage, the group is a "problem–solving

developed parts of the world. Another effect of growing population is the concerning truth of
climate change: changes in climate not only alter the environment, but can alter the range and

systems that can have significant impact on development and the spread of disease. These impacts

70. Path Integration for Navigation
Path Integration Forms of spatial sensitivity among organisms are exceedingly wide–ranging.
Spatial sensitivity among lower animals has been studied in its role in navigation. Many of these
animals exhibit extraordinary navigational capacities. Amoebae have light sensitivities that lead
them to liquid areas that serve their chemical needs. Crickets locate mates using sound. Path
integration, or dead reckoning, is one of the four types of navigation. I begin by distinguishing the
differences among the four types of navigation. I continue by explaining in more detail the second
type of navigation: path integration. Next I explain why one might think that certain types of path
integration are not representational. Last I show why path integration doesn't depend on perceptual
constancies. Path integration is one of the four types of navigation. The other three are beaconing,
landmark use, and map use. Organism's can travel toward or away from a source of stimulation.
Beaconing, or homing, is an organism's movement toward a target. That movement is in response to
a stimulation that derives from the target's location. Beaconing allows organisms to move in
directions that are favorable to them. For example, salmon travel in the ocean for years. After a
couple years, they return to their home streams in straight a line. This is a result of them responding
to certain hormonal changes. Many organisms use another type of navigation called landmark use.

In some cases, lateral force shapes result to good approximation of demand displacements.
Nevertheless, there has not been found any constant loading for exact approximation of local
mechanisms and plastic hinges. Earthquake codes have made it mandatory to use a minimum of two
lateral load patterns in nonlinear static procedure. These two load patterns are chosen to cover
resulting forces in actual dynamic response of the structure. There are two load patterns which are
used mostly in usual studies: uniform and modal load pattern. When using uniform load pattern,
called also constant acceleration pattern, lateral forces applied to the structure are proportional to the
mass of the building stories. This load pattern emphasizes on bottom floors demands more than top
floor demands. It also increases the importance of shear in stories against overturning moment while
modal load pattern emphasizes overturning moment and story demands. The FEMA356 code allows
using comparative load pattern instead of constant load pattern. In this method the load pattern
varies by plastic hinges as the displacements in the structure increase. Obviously, none of these
shapes of constant loading can perform redistribution of inertia forces which occur with the first
local mechanism and change of dynamic properties of the structure. Therefore, it is interesting to
find a load shape which is closer to the variation of inertia forces distribution and gives a better
