This document provides instructions for using the Linear Shaft Motor Application Resource Tool (SMART) software to select the appropriate linear shaft motor. The software contains 13 worksheets, including one to enter application details, one for motor selection calculations, and specification sheets. Users enter load, voltage, temperature and motor details, and the software calculates if the motor meets requirements. It is recommended to verify motor selection due to variability across applications.
Design and development of horizontal tensile testing machine (5kN)Sajeed Mahaboob
In this project, a portable horizontal tensile testing system involving the use of a specially designed tensile specimen is proposed. The system developed was designed to convert the rotation motion of a ball screw into the linear motion of specimen grips that apply a tensile load to the specimen. The frame contains an aligned linear motion guide for the movement of the specimen grips, ensuring the co-linearity of the travel axes. One side of the specimen is connected to a ball-screw block and the other side is connected to a load-cell (which is static) to detect the load magnitude.

1. HCS 2010 online manuals.
2. Data: Data provided for Lab 6
3. Software: HCS 2010
Objectives: The objective of this exercise is to become familiar with operational-level signal timing software. The software you will use is the implementation of the Highway Capacity Manual 2010. General notes regarding this lab:
· The intersection you will be using for analysis is Lake Mary Rd. and High Country Trail. Take a look at this intersection on Google Maps. Draw a rough sketch of the intersection, showing lane usage. Be sure to include a North Arrow, as well as movements (with numbers….use movement 2 for Northbound through). (2)
· Operational data for this intersection is provided in the file ‘Lab6data.xlsx’ open this file.
· The timing data given is for pretimed 2-phase operation. What is the cycle length given? (1)
Background: The HCS2010 software does not exactly duplicate the HCM 2010 methods but it is reasonably close. One difference is in the optimization algorithms, which are specific to the software and are not specified in the HCM 2010.
The software will not design your timing plan for you (It can, but we will not be using that option). It is used as a calculation tool to help you determine which combination of green interval lengths and cycle length provide the best LOS (or lowest delay) with safe operation.
A proper phase plan is a critical aspect of signal timing design. Once the phase plan has been developed, most of the signal timing can be systematically treated in a deterministic fashion. There are several important considerations you need to keep in mind when establishing a phase plan for your intersection:
1. Safety: Phasing can be used to minimize accident risks by separating the competing movement. A traffic signal always eliminates the basic through crossing conflicts present at the intersections.
2. Lost time per cycle: In addition, left-turn protection can also be used to eliminate the conflicts between left-turning movements and the opposing through movement. However, additional phasing can also lead to more lost time per cycle and therefore additional delay.
3. Sat flow rates for LTs: While increasing the number of phases also increases the total lost time in the cycle, a benefit is that this also increases the affected left-turn saturation flow rates. This in turn can lead to less delay.
Lab Steps:
1. Open the HCS2010 software on a PC in Rm. 114 or 113. Open the traffic signals module.
2. When you start a new traffic signal file, a dialog box will appear asking you to verify settings of the intersection. The only setting you need to adjust is that of the forward direction, which is used for arterial analysis. Even though we will only be working with one intersection, you should still choose NB for this. All other settings can be left at their default.
3. You will be entering data in the following sections:

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
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.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
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.

1. Linear Shaft Motor Application Resource Tool (SMART)
Current version V5.2.9E
Thank you for making use of Nippon Pulse America’s Linear Shaft Motor Application Resource
Tool (SMART). This tool is provided to assist you in selecting the correct Linear Shaft Motor for
your application. While every effort has been made to ensure that all calculations are correct,
many variables contribute to the selection of the correct Linear Shaft Motor for your application.
Nippon Pulse America cannot be held responsible for an incorrectly selected Linear Shaft Motor
since we cannot control all the variables of your system. Please verify any information gathered
from SMART.
SMART is a Microsoft Excel Workbook that makes use of Excel’s macro capability. If macros
are not enabled on your machine, SMART will not work.
I. What is available in SMART?
SMART is composed of 13 worksheets. The worksheets are as follows:
1) Read Me (Brief explanation of the Linear Shaft Motor selection software)
It provides an explanation of the Selection Process Flow of SMART. The
“Result” worksheet (see below) is the worksheet used for the selection
calculations.
2) Worksheet (Worksheet to assist in collecting information for entry into SMART)
Please make sure to use the worksheet to collect all information needed before
running the motor selection software section of SMART.
3) Result (Motor selection software itself). Start selection software by double
clicking anywhere on the “Result” sheet.
a. The temperature shown by the calculations is the surface temperature of
the coil, which is inside the forcer.
b. As for the surface temperature rise of the coil inside the forcer, it is rated
for 110K in a 23°C environment.
c. The mass of the forcer is automatically added to the calculations.
d. Please be sure to insert the load, voltage, and the motor you are
considering into the template.
e. If the selected motor will not work within the conditions you chose, you
will receive an error message letting you know what needs to be corrected
before proceeding.
f. The data on the “Spec Sheet” worksheet is used for making the
calculations. We have made every effort to verify that all data on the
“Spec Sheet” worksheet is correct. Please do not modify this data, it will
have an adverse effect on your results.
4) Forcer, Coil temperature difference
This is a list of the standard temperature differences between the outside of the
Forcer and the Coil surface.
2. 5) Spec Sheet (specification chart)
The data on the “Spec Sheet” worksheet is used for making the calculations. We
have made every effort to verify that all data on the “Spec Sheet” worksheet is
correct. Please do not modify this data, it will have an adverse effect on your
results.
6) Move Data
Data for all moves is stored here for use in the calculations.
7) Force - Duty Curve
Will generate a Force Duty Curve for any Linear Shaft Motor. When the Window
below is displayed, select the correct motor and press OK. The Curve will be
generated.
8) Tandem forcer interval

12) Principal
13) Velocity Ripple
3. II. Software operation explanation for “Linear Simple Selection, Ver5.2.8E”
1) Please open “Linear Simple Selection, Ver5.2.8E”
2) When you see the message that macros are used, please click the “Enable
Macros” button for the program to work correctly.
3) Please select the “Result” worksheet tab.
4) Please double click the center of this worksheet.
5) You will be asked the units for which to make calculations.
6) You will next see the input selection, which is shown below.
4. 7) The friction coefficient range for most linear guides is 0.02-0.03; however, the
values for residual pressure, seal resistance, etc., should also be taken into
consideration. You should calculate your resistance settings before entering your
friction coefficient. For example, we would like to move a load, M1. The power
to move the load is M2. We need to calculate the friction coefficient. The formula
would be M2/M1. Please see Appendix A for more information about the friction
coefficient.
8) Enter the load information. Only the mass to be moved needs to be entered, the
mass of the forcer is automatically added to the calculations.
9) The Voltage should be equal to the input potential of the servo driver you are
using.
10) Enter the environmental temperature data.
11) Enter the allowable temperature. In this case, the allowable temperature is equal
to the temperature of the coil inside the forcer.
12) Choose whether your application will be horizontal or vertical. This factor is
important for the force coefficient. The amount of force required will be different
for horizontal and vertical. For vertical applications, force will keep the forcer
from falling. Please carefully choose your force coefficient. If you set it too high,
the coil will overheat and the motor will cease operation. If you set it too low, the
forcer will not stop moving, as you require.
13) Select the designated motor.
14) If you do not enter all the data, you will receive an error message after you
attempt to calculate the motion.
15) Click the “Define Move Profiles” button
16) The Define Move Profile window will open (see figure below).
5. 17) Please enter the stroke length you would like to have.
18) Select if Motion is defined “By Setting Time”, “By Work Velocity”, or “By
Acceleration”.
19) Input the appropriate variables for your movement.
20) Enter the amount of time to pause before beginning the next motion in the Interval
box.
21) Click on “Save Current Move”
22) If this is a new move which has not been named the following window will
appear.
6. 23) Enter a Suitable move name in the box, in this case we will use “1”, press OK.
24) If additional operational patterns are needed, please repeat steps 17 – 23.
25) After you have saved the last move select the “Define Motion Profile” button the
following window will open.
7. 26) If an additional pause is needed for all moves, for example settling time of the
driver, this should be entered in the Interval window. Note this time is added to
the move pause time entered with each move.
27) Select pattern number to be used.
28) Select “Forward” OR "Backward" if in Horizontal mode. In this example,
“Forward" is selected.
29) If you are in Vertical mode your options are “Up” and “Down”
30) Then click "Next ".
31) The calculation for that move is performed in the background.
8. 32) For more additional moves repeat steps 27 - 30
33) The calculation can be repeated indefinitely under these conditions. When
finished select the “Calculate – End” button.
34) Your results will be displayed and can be printed.
III. Supplementation
1) It is possible to have as much as a ±10°C error in the temperature calculations
displayed; therefore, it is recommended that you verify all data before selecting a
Linear Shaft Motor.
9. IV. Appendix A
1) Coefficient of Friction
Extreme care is needed in using friction coefficients and additional independent references
should be used. For any specific application the ideal method of determining the coefficient of
friction is by trials. A short table is included above the main table to illustrate how the
coefficient of friction is affected by surface films. When a metal surface is perfectly clean in a
vacuum, the friction is much higher than the normal accepted value and seizure can easily
occur.
