Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

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.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

DESCRIPTION: The SR60A Series PWM servo amplifiers are designed to drive brushless motors with 3-phase sine
wave current. An on board digital controller generates the 3 phase sine wave signals from the resolver input. The
encoder emulation outputs (A, B and I) continuously produce signals equivalent to a 1024 line encoder. All models are
fully protected against over-voltage, under-voltage, over-current, over-heating and short-circuits. The SR60A series
interface with a digital controller or can be used as a stand-alone drive. Only a single unregulated DC power supply is
required. A red/green LED and a single digital output indicate operating status. Loop gain, current limit, input gain and
offset can be adjusted using 14-turn potentiometers. The offset adjusting potentiometer can also be used as an on-board
input signal for testing purposes when SW1 (DIP-switch) is ON.

X does not affect mode.
COMMUTATION DETECTION MODE (SW1-5):
In commutation detection mode the amplifier will automatically detect the optimum phase angle by performing a test
move while monitoring motor position. Phase-offset and pole-count are stored in non-volatile memory for further use. In
this mode the motor shaft MUST BE de-coupled from the load and free to move. It is also recommended to secure the
motor to avoid damage or injury. CAUTION: Sudden motion will occur in Commutation Detection Mode. Do not
activate commutation mode while the motor is attached to the load and do not touch the motor shaft during the
test move. To start commutation detection, follow the steps below.
1. Configure the amplifier for current mode (see table in block diagram)

www.electromate.com
sales@electromate.com
Failure to do so may severely damage the motor.
3. Apply a reference signal such that a current larger than the continuous current of the motor is commanded.
A. If the on-board test pot (Pot 4 with SW1-1 ON) is used as the reference signal, the pot must be turned
CCW from the middle (0V Command) of the 14-turn pot.
B. If an external reference signal is used, this command signal must be a positive command (i.e. positive
voltage into +REF must be positive referenced to Signal GND).
4. Power up the amplifier:
A. in a disabled state (via enable/disable input P1-11 or DIP-switch SW1-6),
B. with SW1-5 OFF,
C. and with P1-10 (Burst Mode) open.
5. Once the amplifier is fully powered (with LED red), set switch SW1-5 ON.
6. Enable the amplifier (the LED will remain red).
7. Pull P1-10 (Burst Mode) to ground. The LED will turn green. At this time the motor will make one and a half
revolutions CW and one and a half revolutions CCW. If no motion occurs, power down and repeat from step 1.
8. Upon completion the amplifier will automatically disable (red LED).
9. To complete detection mode:
A. power off the amplifier,
B. set switch SW1-5 OFF,
C. and release P1-10 (Burst Mode).
D. remove command signal (set Pot 4 to middle if it was used in step 3A)
10. The amplifier is now operational.
BURST MODE (Pin P1-10)
In Burst Mode the amplifier will send an encoder pulse stream to the motion controller equal to the amount of pulses
between the resolver datum and the actual motor position. This allows the motion controller to register the absolute motor
position (within one motor revolution). The Burst Mode sequence is as follows:
5. Disable the amplifier.
6. Pull Burst Mode input to ground (can be done immediately after amplifier disable).
7. Upon Burst Mode input pull-down, the amplifier will first send a single index channel pulse and then 2 channel A and
2 channel B pulses (8 counts). The Burst Mode input must be pulled down for at least 2.1 milliseconds to ensure this
initial stream.
8. Upon Burst Mode input release, the amplifier will stream the appropriate amount of pulses (from datum to actual
position) with channel A leading channel B. This stream will complete in 15 milliseconds (channel line width is 3.4
microseconds).
Caution: motor shaft movement during Burst Mode will not be registered! The motor shaft must remain in position during
Burst Mode in order to work properly!
APPLICATION NOTE: For proper operation, P1-6 and P2-14 must be connected to the signal ground if they are not
being used.

CURRENT LIMIT ADJUSTMENTS:
These amplifiers feature separate peak and continuous current limit adjustments. The current limit adjustment Pot 2
adjusts both peak and continuous current limit at the same time. It has 12 active turns, one inactive turn at each end and
is approximately linear. Thus, to adjust the current limit turn the potentiometer counter-clockwise to zero, then turn
clockwise to the appropriate value. In many applications it is sufficient to use only the DIP-switches for current limit
adjustments. SW1-3 reduces both peak and continuous current limit by 50% when OFF. SW1-4 reduces only the
continuous current limit by 50% when OFF:

P1-9 is the input to the internal current amplifier power stage. Since the output current is proportional to P1-9, the
adjusted current limit can easily be observed at this pin without connecting the motor. Note that a command signal
must be applied to the reference inputs to obtain a reading on P1-9. The maximum peak current value equals 7.25 V at
this pin and the maximum continuous current value equals 3.63 V at this pin. If SW1-3=ON, peak rated amplifier
current = 7.25 V. If SW1-3=OFF, ½ peak rated amplifier current =7.25 V. Example: using the SR60A40 with SW1-
3=ON, 60A=7.25V and with SW1-3=OFF, 30A=7.25V.
The actual output current can be monitored at pin P1-8.
